Ok ... sorry for the stupid question ... but here is my situation. Recently a lady backed her truck up into my car and messed up the whole drivers side door and moldings. The body shop took about 4 weeks to get everything fixed and painted, but it look like when they painted they did not seal off the engine bay. I have a powder residue all over my engine bay. I have been trying to wipe it all off for a few days now, but cant seems to get in all the nooks and crannys. Is there something that i can use to spray down the entire engine bay (that will not hurt anything). Or is it just a lot more towling and elbow grease?
