I just got old first act electric for $5... I want to mod it, any good ideas? IT has a single humbucker with a tone and volume pot.

ITs got a Telecaster style body, with a strat style pickguard.

IT used to be black, but I sanded the clear coat off of it, and it came out a grey, with a vintage finish, like it has been played a lot and worn out.

I was intending to refinish it black, but I like the grey so I am leaving it, any ideas to seal it without making it shine.

I think I will add a kill switch.

any ideas for cheap mods?
