Rattle Can Self Etching
 

Is it safe to use rattle can self etching before spreading filler? Or should I spray it. I want to do some of the filler work myself to help prep for paint and I know rattle can is a big no for finish work but wasn't sure if it's the same for under the filler.

never etch prime under filler, or apply filler over etch primer. if metal is clean properly, putting filler on it is no issue. If your concerned use a epoxy primer on the bare metal areas, then sand with 120-180 then do filler work

woops I feel like an idiot, I knew it was epoxy no self etch but for some reason kept telling myself self etching. Thanks for the heads up, any reason epoxy in rasttle can would be an issue?

What type of "epoxy" is it? There are a few companies that make "epoxy" paints and primers in cans that are nothing more than lacquer.

There are also a few companies that are producing legitimate 2K epoxy primers in rattle cans. However they're $20 a pop.

I'll buy whatever need be, I have an autobody supply shop around the corner.

Rattle cans are a 1 part system. Your not getting the hardener in a rattle can. An epoxy is a 2 part material so you'll have to spray it like normal.

there are a few rattlecan 2 part primers out there that are one time use. they have a pouch in the bottom with hardener in them that you have to puncture. then shake and spray..

Hey GM any pics of your car you can share?

standox makes a 2 part epoxy rattle can as well, one can goes alot further then you think
its called ep pre coat

thanks for the info guys!

its no car, but a truck :thumbsup:

anything that is not catalized under filler,is a bad idea, I'm sure some old shool butchers will tell you it's fine,just hose on some lacquer primer,git'r dun, DO NOT listen to them! I'f the primer you're thinking about using does not need catalyst/hardener,find one that does

i will second that

Ok, the only reason I was even considering it was to make sure any tiny pinholes or edges had some primer in it before I spread filler. But it was more of a curiosity than anything, I'll probably let my body guys take care of it.

Anything in a rattle can should be stored in a... http://apps.co.marion.or.us/imagegal...%20can_RGB.jpg
