Quick paint question
 

I may be starting a new project soon and I'd like some paint advice. It'll be outside on a slab. Car cover on it in between work days. I want to attack each panel one at a time to fix and uncover PO bondo, rust, ect. I need to protect it until I paint it in a few months.

Are the primers in spray cans worth a darn? Is there one you guys recommend? I'm gonna start at the front, engine compartment, and work my way back.

Re: Quick paint question
 

Do you mean good enough to temporarily seal the panel or good enough to be the foundation for your future paint job?

Re: Quick paint question
 

primers absorb moisture as far as I know, unless your using the 2K spray paints. Even those I,m not sure of

Re: Quick paint question
 

I want to seal it. When its all done I'll go back over the whole car and then I can primer, sand ,paint all at once.

I've had good luck with Rustoleum red oxide. I have Tractor Supply red oxide on my '67's cab and it's holding up after over ten years. But they switched suppliers since then and I've never used the new stuff

I've seen that stuff, not sure how well it will work with auto paint.

What I've done on a number of projects is strip door/hood/fender to bare metal and take them to a local body shop and spray them with 2K epoxy. Then store them out of the weather. Same thing with the cab/body. Typically the body shop since they spray the primer every day it's good stuff. I would not trust spray bomb under a base coat paint.
Also the body shop can offer advice on the sealer and paint so it works together.

Strip/80 grit on a DA/Epoxy, keep out of the weather, should be good.

Re: Quick paint question
 

I was thinking temporary. I agree epoxy primer is the best for this. I've never checked but I imagine a paint supplier could fix some up in spray cans.

Re: Quick paint question
 

You can get epoxy primer in a spray can....you puncture an internal activator and it will last about 3 days in the can....
it's kinda pricey so be ready to paint several pieces while it's still useable

The recoat window closes pretty quick on the epoxy primer I normally go ahead and coat with high build after the epoxy dries usually the next day either way [any ] way you go you should keep it out of the weather if you can but I do have primered parts out side my self now. I always recoat weather it is just epoxy primer or high build if it has sat any good length of time, I will sand 180-220 grit then two more coats of high build. Also, any time you put spray can primer on a truck[or toolbox even] I would take it back off and reapply a primer designed for auto use in a paint world. I'm sure that there are tons of paint jobs that have spray can primer under them but why take that chance when your spending what could be a goodly amount of money to buy all the stuff needed to paint one. I love Omni[PPG] and love the omni pro line of paints[or is it omniplus?] I cant ever remember but either way it is great stuff you can feel the diff between the regular omni and the pro just by shaking the can. Or at least I can tell the diff by feeling without looking at the cans. Jim

Working outside in those conditions here's what I do. First I wipe all the bare metal down with metal prep with zinc. Apply 2 coats aluminum pigmented moisture cured permanent rust sealer/primer,{non leafing} apply epoxy or urethane surfacing primer over it the same day. Then go from there. Epoxy primer is waterproof but not airtight , that's why it contains a zinc as a rust preventative. Zinc Is sacrificial so if you left it in epoxy primer for a year outdoors there's a good chance you might have rust bleed thru.

Re: Quick paint question
 

Good question. I’m facing a similar situation. I can’t do all of the metal work in one day, so what do I use as a coating after I do one spot/job but still have weeks or months left before I do a total sand down and spray the epoxy?

Re: Quick paint question
 

There are metal preps that contain zinc. If your wipe a panel down It will clean and dissolve rust and it'll stay rust-free for months indoors. Outdoors the time span would be shorter , you would have to reapply it like every month. Some epoxy primers you'll have to scrub the residue off .,others you don't. But epoxy you got to be above 60°. I personally prefer urethane primers .
