I haven't really had much experience using bondo (which is probably a good thing) But recently I've run into a bondo related problem that may be not too big of a deal, but I'm a bit nervous about it. Basically I share a house with my lady and a buddy of ours and one day my buddy decides he's gonna take an old motorcycle gas tank and get rid of all the bondo on it with a grinder. My car is all torn apart and taking up most of the garage. interior is out, hood open, carbs dont have air filters on. basically everything is wide open. So this dude winds up grinding away on this old tank, covering EVERYTHING in the garage with bondo dust. and now im worried because my ENTIRE car is covered in the shit. And I mean everything. my whole interior is out of the car and covered in it, the hood open, its all over the motor, probably all in the carbs. Im sure all the work i just did rebuilding my carbs is for nothing if any of that dust got into my float bowls. so im already pissed. but do i have to worry about that shit hardening again if it gets wet? like if its in my carbs and i dont tear them down and rebuild them again just in case, i'll wind up with dried crusty bondo in my carbs? those holley single barrels arent cheap. of course i'm gonna make him clean it up but i know he'll half ass it so it's almost pointless. sorry if it seems like a dumb question but i tend to always think of the worst possible scenario for anything. just trying to get an idea of how much clean up work is ahead of me.
