a few questions.

im about to prep the car for final spraying. when i had it prepped in primer before the metal rusted underneath the primer, which is a bummer.

 

so... what would i do to prevent this happening again???

 

i am thinking about sanding the paint off the arches until bare metal where the rust is, then wire-brush the nobbly bits... where do i go from here?

bearing in mind all this has to be done outside on the driveway.

 

i have some stonechip paint which says its an anti-rust, but do i need to treat the rusted metal with something like KRUST first, then add the stonechip-primer-topcoat then start with the filler on top to get it smooth?

 

whats the best way of going about it, i want a temporary top coat which i can sand with 800-1000grit to be ready for my sprayer to get his primer to key-into. which isnt porous so the rusting doesnt happen again before spraying.

 

guy is spraying in 2pac doing primer, rubbing down, then top coat. ta

dont just use 'primer' try to use etch primer epoxy or summat like that, as primer doesnt repell rust if left bare, i.e no top coat, it will make it worse, thats why it had rusted underneath the primer.

 

use rust prevention on bits you have repaired and are prone to rusting, such as hydrate 80,rally design sell this and its the nuts!

 

hope i have kinda helped?

set about the rusty bits with an 80grit pad on the D/A until youve either got nice shiney metal or a hole cut out any remaining thin crappy metal and let (weld) in nice new shiney stuff "dress" the welds

 

if you have no holes once its back to shiney etch prime it
