Paint stripping P/E parts

[countach79]

I'm not liking the paint job on some p/e brake disks of mine

can i just put them in brake fuid? and will it have any effect on the 5min epoxy?

cheers

I don't care for brake fluid because it has an oily consistency and can weep out of the vents and ruin the new finish. I just rub it off with a rag soaked in lacquer thinner for most everything now. (Do it outside so you don't fume up the house.) Since the paint is fresh and on a metal surface it should come off without too much effort. Do try to avoid soaking them.

Edit: For the record, lacquer thinner works here because the parts are p/e and not plastic. Lacquer thinner will turn polystyrene plastic into a quivering puddle of goo!

A while ago i was really high and soaked a body to strip it in thinner. I was going to leave it in there for 20 min or so and forgot about it for a day. Next day it defenitly was a puddle of plastic.

thanks guys!

would the thinner have any effect on the epoxy used to glue it all together or would it still hold?

Lacquer thinner can't hurt cured epoxy. Once epoxy sets individual molecules become irreversibly cross-linked through chemical reaction like a tangled up pile of fishing net. The paint, on the other hand, is just pigment suspended in a binder left over after the solvent evaporates. The binder holding it together will soften and dissolve when it comes into contact with the lacquer thinner (another solvent).

But don't just take my word for it. Experiment a little.
