PPG Epoxy Primer

So im gonna take my cab and doors down to get sandblasted probably next week. The bed is completely down to bare metal. I am going to be putting the cab, doors, and bed in one coat of PPG 2k Epoxy Primer. Does anybody have a general idea of about how much Epoxy Primer I am going to need? thanks in advance-----Forgot to mention the cab is going to be sprayed inside and out...

 

At the least an activated gallon. One gallon barely did my 48 Chevy car.

 

I would think a GL and the Catalyst would be enough. Thats One and a third gallons right?

 

i would say sniffinpaint is right. never cut yourself short, it takes alot to cover inside and out.

 

If you use a hvlp gun, minimize overspray, and aim right, a gallon is more than enough.

 

If you use PPG's DP line of epoxy you can reduce it 1 quart per gallon. It mixes 2-1-1/2. The 1/2 is the reducer and makes it spray ALOT slicker.

 

check the info sheet before using PPG over blasted metal. You might not have any trouble but I've heard of problems with solvent pop later.

 

I've never used the stuff, but would like to know if plastic (Bondo) will stick to it, or should deep pits be filled first?

 

If it is the DP 90 LF ( lead free ), it is a completely different beast than the old great DP 90. I would use 2 coat, not just one. That way you get good coverage for sure.
Do you plan on sanding back off or scuff sanding for mechanical bonding to wipe mud over it, which you will have to skim the whole car lightly if you want it arrow straight, you should sand most of the mud off though, and you will be breaking through all over the place with just one coat.

and yes from above, the HVLP will make it go a lot farther.

 

I'd been spraying PPG for over 20 years, just my oponion... i'd go with DP and just go over the ruff spots with 2K. If you have pits and want them covered without shrink back, bondo(big pits) or 2 part PPG glazesmall pits. Personally i dont bondo over primer, i know you can, but i dont. reduce the DP a little ***2 Qts of DP and a gal. of 2k*** follow your tech sheets

 

I have always used self etching primer first then regular primer/sealers/epoxy primers. Im not a expert but I wonder why "they "call it that...hense self etching?
