[freezing14]

i am finaly done fixing the swiss cheeze on the car , it is all gone, i will be soda blasting the car within a couple of days and i will be putting the primer on myself to be able to do the most of the body work myself and i have looked into the different primer and now i am confused?? (IMG:style_emoticons/default/huh.gif) (IMG:style_emoticons/default/blink.gif) (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) i will be using the omni line of paint from PPG and there is a couple of different primer--
the epoxy etch, but it contains chrome ( very toxic) so reject as i have a home made paint booth
the regular epoxy but apparently it is not sandable ( wtf it means)
then there is the high build 1K no epoxy ??
then the high build 2K epoxy

the car is strait and very little pitting on the outside i had to joint the quater panel half way and i did a couple of patch but they are but weld so very little bondo

what is the best price versus quality way to do??

I know i have to primer, putty, primer and then paint , which one should I use for which

thanks you very much for your help

I'm in the middle of putting epoxy primer on my vehicle. For me, it's the way to go.

I don't know much about paint, but I'm learning. Here are a few things I've learned:

The word "primer" means a lot of different things......

-Epoxy primer is great over metal or over old paint after you've scuffed it. It's not sandable. It doesn't absorb water (key point) and seals against water getting to the metal. It's tough and can be topcoated directly or left as a topcoat (for your underbody or interior of a race car).

-You can put body filler on top of the epoxy primer... before 7 days (depending on your epoxy primer)

-Once your body's flat or straight you should use a high-build primer and sand it down to smoth out the sanding scratches

-Then you need to seal that since both the filler and high-build sandable primer can absorb water, so you use a primer sealer

-Then you can put on the color coat, followed by a clear, if desired.

See, "primer" can mean a lot of different things......

There are many variations to this process and not all of them will work, but some will. You're also not supposed to mix paint systems.
