My gf has this mazda B series. It apparently was in a wreck and re-painted. They did a crappy job and now there are tons of tiny cracks in the paint. On the roof it cracked, peeled, and, has started rusting. The rust is not too terrible, metal is fine underneath. If you pull back the rubber around the windshield its rusted under there too.
She wants to just spend a minimal amount of money to paint this with a rattle can and hopefully prevent further rust. What would be the best thing to do and primer/paint to use?
There are many primers and stuff that say preps rusty surfaces? I say the rust all needs to go first or it will keep eating the paint?
Not looking for a perfect fix. Just need to get a few more years out of this truck and cover up the bare metal.
Also, there are all the hairline cracks where I think may eventually become more pealing and rust. Would keeping it waxed prevent it from getting worse?
Thanks in advance!
