I have taken the giant spoiler off my car, I'm left with 4 bolt holes in the rear. What should I fill them with before I get the car painted??
duct tape tends to do the trick, or if your the fancy type, you might want to just get them welded up, its not a big job for a shop to do, so won't blow the budget if you need to pay someone to do it.
a few ways to do it.. weld it like people mentioned.. other option is a product called metal mend. its has fibreglass strands in the product. -knock the holes in so they are recessed -remove paint around holes -tape back of holes up -clean surface with prepsol/similar -apply metal mend (follow instructions, similar to bog) -allow to cure until almost very hard. -sand before the metal mend hardens all the way. -remove tape -clean all sanding dust off using prepsol/similar -apply bog on top of metal mend -sand bog when 100% dry -check bog to see finish, if not happy, bog and sand again -clean all sanding dust off using prepsol/similar -primer -sand primer -paint cost metal mend - $20 a can bog - $20 a can prepsol/wax and grease remover - $10 a can primer - $15 a can paint - depends if a shop is doing it, or your doing it yourself. welding is good.. problem is some people cant weld for crap and with excessive heat will buckle the panel. personally i would get it welded. ive done the above method many many times on plenty of cars and i have not had a problem. my friend tried this and had a problem because he didnt clean the surface with prepsol and it started flaking off as it wasnt sticking very well.. as always i take no responsibility for you screwing up. my advice is a guideline which works for me and may not for you.
