I have real skinny and long fingers and I have been trying to do bar chords for a while but I can almost never get it right cause something always buzzes or mutes or doesnt sound right. So I was thinking, do those tubes you slide on your index finger work good? Don't know what they are called but at least if I had that I could play simple bar chord songs while I practice without it some more.

And I know that this is a stupid question to ask but are they considered lame in the guitar world?
you are talking about a slide.... and yeah slides work great, but they aren't used for what you are thinking about doing. a slide is certainly not considered lame if you are using it correctly, but i must say that if i saw somebody using a slide just to play barre chords in standard tuning i might snicker

Yeah man a slide and they arent for people who cant do bar chords but i recomend getting one they sound awesome once you learn how to use one. Given the right amount of time youll get it just practice it. a song you can practice that has bar chords in it is MAma im comin home if your into ozzy.
Two things: it's a slide, and (just for the record) you would never put one on your index finger--you'll appreciate that piece of advice when you get to point where you want to play with a slide.
Just practice in short sessions, like half an hour blocks, and take a break in between to rest your hands. You get really calloused fingers after a while.
Or take up classical guitar, it has lovley soft nylon strings
You're half right. If you play in an open tuning, a slide wouldn't be a bad idea. But for standard tuning it won't work that well. As others have said, keep practicing. I have small fingers and I can play any barre chords with .014's on my acoustic, it just takes time to build up the strength. Find a song you love that uses barre chords and practice it.

Try smaller gauge strings.

I've played with 13's forever and wanted to up the challenge since it's my practice guitar (I play everything on it, so when I go to electric it's a snap). Well I put them on and no neck adjustment was needed at the time (not to say it wouldn't form later) and the nut was just barely big enough. I loved them but I went back to 13's cause I was bending the G string and it snapped. They're just too expensive and I play my acoustic too much.
