I've painted my guitar white using spray cans. After I put on about 8 coats of clear, I sanded with 600 to get rid of the heavy orange peel effect. Now the guitar if all spotty with flecks of flat and gloss on it. It feels smooth but looks rough and bumpy. Does anyone know what this is or what to do?

the best bet, is to not use spray paint. try actual instrument paint.

Can you read? Honestly, that's a real question... The guitar is already painted. I need help now.

also, p o e, what kind of paint should I use? Because "instrument" paint is rather unspecific. Post me a link to where I can find the stuff.

i dunno, i just prowl this forum to look at builds and such.
but i can tell you spray paint probably isnt a good idea for an instrument.

Yes, I know that. However, in the absence of a better suggestion than spray paint, you really aren't helping anyone.

Also, pics will go up as soon as I find batteries that work. I have 26 AA batteries in my home. None of them work. I cannot even begin to understand why god hates me as much as he does.. but he has chosen to express this hate in the form of low quality Chinese made batteries. cheers

wow... i usually charge for all of this info but hey. i'm a nice guy.

1: sand it down and start over with the suggested paint.
2: search for the paint and research all possible products of quality.
3: paint it slowly and carefully. also look on UG for possible step by step articles.
4: 26 AAs are crazy! Duracell rechargeable batteries amazing.
5: I dont think God hates you.
6: Get checked for lead poisoning due to the purchase of current Chinese products.

600 is a fairly low grit. Try working your way up in grit to Micro-Mesh.

Edit: many people paint with spraypaint. It's acceptable; it won't kill your guitar. Don't expect a professional finish, though.

Stop. You don't have to start over. Read my post. Use a MUCH higher grade of sanding paper. Work your way up to the highest Micro-Mesh, and you'll have a beautiful gloss.

i don't quite understand people saying no to the spray paint.. I mean even Stew Mac sells spray paint. unless you are using sonething other than nitrocellulose or poly you should be fine. And no i don't know about the bumps i was just trying to help on the spraying front.

So how do I tell if my paint is nitro or poly?

People in Canada are mostly ****ing retards, I walked into my home depot and they no idea what sanding sealer even was. The had never heard of tung oil, and the guy told me that I didn't need anything except one can of white spraypaint to paint my guitar.

I guess I should have known better.

Chad, what sandpaper should I use?

I can almost guarantee you that your spraypaint is poly. This isn't a bad thing; this simply means that it won't really age with the guitar. It's not Canadians, by the way. It's just Home Depot. They're easily the most unhelpful hardware store in the world.

Use extremely high-grit sandpaper. Even 2000 will leave a satin-like finish to your guitar, dry. Wetsanding is an option, but be VERY careful. Plug any small holes in your guitar that bare wood with wax. Use lukewarm water only, as well. I recommend simply dry sanding your way to a perfect gloss with Micro-Mesh from Stewart Macdonald. Look it up.
Sincerely, Chad.

ok. thanks guys. Also, could the spots of gloss and flat be where I've sanded through the clear and into the white?

And also, someone said I shouldn't expect a professional finish. Well..... I do. What can I do aside from taking to a professional to achieve this?

Could be. How hard were you sanding?

If you expect a professional finish from an amateur job, you're dreaming. That's like expecting an average home painter to do a mural of Starry Night on your wall. It just doesn't work that way. Practice makes perfect. Your first paint job will be bad, your second will be better, and so on. You can either scrap this and paint guitar body after guitar body until you learn every nuance, or you can simply accept that this is your first attempt and essentially an experiment.

Edit: for example, the first guitar I ever painted went great, until I was wetsanding with 1200 grit. I decided that running a hose onto the guitar was the best way to paint it. Big mistake. Every single hole for a screw in the guitar exploded with cracks and fault lines. I had to not only wait for it to dry (around a month before it was back close to normal), but I had to strip the entire thing and start over. Deal with disappointment; it's a part of life.
Sincerely, Chad.

yeah I geuss so. Ok but I still need to know, what do I do now? You said go with finer grit, so what do I do? Do I start right off the bat with 2000 grit, or do I work my up? I would like a definite, tried and true plan so I can do this right.

Two paths:

Wet Sanding:
1. Plug all holes showing bare wood with wax.
2. Prepare a small dish of lukewarm water.
3. Gently dab the paper into the water and begin sanding. Remove when dry or clogged with material and soak again.
4. After sanding the guitar once with 600, step up to 1200 wet. Keep going upwards until around 2000.
5a. There will still probably be scratches in the guitar's finish, so finish by buffing with pure carnauba wax (the hardest wax you can buy; not liquid. You will need to run a wheel against a chunk of it, then run the wheel on the guitar).
OR
5b. Continue wet sanding with the highest grit of Micro-Mesh.
6. Apply polish for shine.


Dry Sanding:
1. Dry sand guitar with 800 grit, then 1200 grit, then 2000 grit, and so on and so forth.
2. Finish all the way up to the highest grit of Micro-Mesh.
3. Apply polish for shine.

Realistically, both will produce a similar finish. Wet sanding is faster, but could be more costly, not to mention potentially dangerous.
Sincerely, Chad.

would doing a 600 or 800 grit sand, or very fine grade steel wool between coats help so as to not build coats on coats of imperfection? thats how i finished some furniture(steel wool) that came out looking good, and i was laying thick coats of polyurethane down with a paint brush. no brush strokes, no orange peel. only a bit of wood grain showing, but was to be expected with the finish of the wood

wet sanding sucks. my dad used to have me wet sanding cars for hours when he owned his autobody shop... sanding is the one aspect of building i really dont look forward to

OK thanks a ton chad! I have 5 days off as of now, so I'll go with the dry sanding way. Hopefully I can get what I need locally, and if not there is always stewmac.

Once again thanks so much. It really helps to have someone who knows what they are talking about.

sand it back to wood, use sanding sealer then re paint it with 2 pack.



why the hell would I do that?

Also, chad I'm using the method you suggested, but using wet. Uhm... I couldn'tfind any bare wood on my guitar... I didn't mask anything when I sprayed so, I guess theres no bare spots.

So far it is going well. I'm starting with 600, and it is working.

What do you mean when you say micro mesh? I'm having my dad pick up some 3M Flexible Polishing Cloth (4000, 6000, and 8000 grit). Will that suffice?

Micro-Mesh is just the Stewart Macdonald name for high-grit polishing cloths. I like theirs because they are extremely durable, but this would only concern you for shop use.

Those 3M cloths will certainly work. We used them all the time in the old repair shop I apprenticed in. However, remember to step up gradually in grit. Go from 600 to 1200 to 4000 (simply for the sake of preserving the coat; you'll probably have more sanding to do with these large intervals).

As far as bare wood goes, this includes small holes (screws for pickguard, string holes, etc). Trust me, get water (especially cold) into the pickguard holes of a guitar, and you won't be happy. You can simply put a bit of soft wax in there to plug it, and your screws will go right through it when you attach the pickguard.

I hope all goes well. Try not to forget to pick up some carnauba wax (pure; it will be in solid form). Buff that onto the guitar, and it'll shine like fresh from the factory. You should even be able to do this after wet sanding with 8000, though professional jobs go much higher in grit (to try and get a mirror shine even without wax).

Go slow, think carefully, plan ahead. You'll enjoy your time spent a great deal more with a careful job.
Sincerely, Chad.

arnt you meant to let the clear to cure for sometime so it hardens
i think the longer you leave it the harder it gets it like wen you paint cars you bake them to speed up the curing process. I think if you dont let it cure its easy for dents to occur especially whilst wet sanding.

And use cool water cool down the heat produced by friction between the guitar n the paper

Do not use "cool" water. The water in the wet sanding process isn't there to cool anything; it's there for lubrication. There's one thing that wood likes less than warm water, and that's cold water. Cold water is a fairly sure way to make your guitar explode (if it happens to work its way into a nice little crack or hole).

Assuming that he has used a polyurethane finish, I guarantee it has cured, by now.
