u would prolly think i would know the answer to this, but im striping down a tx coupe for a complete rebuild, its goin back to bare metal, but it is not being sent to the panel shop to be prepared yet, but i am paint stipping and sanding it back to bare metal myself, im wonding cos its not in the best spot for a project gem im wondering if i should strip it and then spray it with etch primer to stop it rusting, mind u there is welding and bogging to be done.
suggestions please, as i have more work to do before it can go to the panel shop, but i want it stripped back ready to go

etch primer is still porous.. you need to do a panel at a time..and etch/undercoat, to stop surface rust , or strip it all back and take it to them directly.. the more surface rust you get.. the harder it is to prep for paint

strip it and etch prime it, etch prime stops water better then normal primer. (being a spray painter apprentice i thought u would know this)

but still cover it up good witha tarp. also yo should etch prime b4 u putty and fill anyways. filler should not be applyed to bare metal

true.. undercoat is more porous.. i've always put it on scarcly (etch)so it tends to bond better.. but everyone is different! Smile

well i took my wagon back to bare metal and it was 10months before it was painted. i just took it to bare metal made sure all my welding and repairs were done made sure there wasnt a single imperfection then coated it once with 2pac etch primer. it then sat in the shed for a month or 2 before being taken to spray booth. in my opinion u would be silly not to etch it and/ or prime it.

read the label, do NOT apply to bare metal...

i was referring to etch priming then primer filling gene,
he may as well do both and then all they have to do is top coat it.

seems logical to me

lebel smabel! what happends when the paint u applied it to flakes off? known to happen with old 2pack, all ur bog and body work comes undone, it is a rule in the industry that you stip the patch back to bare metal, apply the filler, then undercoat

after stripping ym car i had a bit of surface rust. I sanded it out and anything i wasnt sure of i used rust converter. Then re sanded and prep washed. Etch primed it with 2 coats and has been sitting in the shed un covered for atleast 4 months now and havent had a problem with it yet so far.
