PPGs omni epoxy primer

[65post]

I started using the PPG Omni epoxy primer a few months ago.I was just wondering if anyone else has used it and do they like it.

I've used Omni single stage urethane. I thought it was garbage, really.

I have used it , 65, and have had no problems.  We I asked about whats the difference between it and the DP series , I got its the same , just cheaper.  Not sure about that. I was wondering myself if they are leaving out the zinc chromates or other materials.  I done a rusty trunk years ago in DP40 to stop the rust till I could cut it out and replace. Well I have done no more but it still looks like I painted it last week.   Not sure if the Omni would do that.  Anyone in the know.........J

Just got done painting my car w/ Omni line.  This was my 1st foray into using urethane; I'd painted a couple of cars w/ lacquer way back when including this car about 12 yrs ago.
Had no problems w/ the epoxy or the high build. IMO (not that I have much to base it on), good paint for the $.

I will, however, recommend AGAINST using their MBC color.  Very poor coverage.  I had a professional spray the B/C initially & the results were TERRIBLE for a variety of reasons.  So bad that I decided to sand it down & do it again.
After experimenting on an old rusty, dented wheel barrel (I suppose it woulda been prudent to do that 1st)  I decided to try again myself.
I'd say the results are mediocre.  Certainly very passable, but not as awesome as I had hoped for (hey, at least I can say it was better than a pro ).

From what I had read prior to selecting Omni, I think I read nothing but good comments about their clear but some people did say the colors covered poorly.  The pro sprayed 3 coats & once you got it out in the bright sunlight, it looked like crap.  I sprayed 4 (after sealing the old stuff w/ grey epoxy which was darker than the high build - car is RR1 metallic burgundy BTW)  & there's slight color variation detectable iin  very bright sunlight.

When/if I paint another car, I think it would be prudent to try another line.

But if you're only interested in the epoxy primer, I have no complaints about it, but then again, I really don't have much to base any comparison on.

Should have used the red sealer (dp74) if spraying burgundy for better coverage, also using 2 different sealers or light sealer & or different amounts of coats & you will see different colors. Typical. LEON.

My thought was to use the Red sealer, but the counterman recommended against it due to price  (a Qt was almost as much as a gal of Omni MBC).

To clarify -

initially I stripped the car to bare metal & applied the epoxy sealer.  I then had to do a few sessions of High Build (I forget the #, but it was light gray).  My neighbor then sprayed the MBC directly over the high build (then cleared over that).  This resulted in an unacceptable paint job IMO, so I did it over.

2nd attempt, I sanded down the clear w/ 400 grit.  (Note that on the lower portions of the car primer was visible and I sanded thru the clear in a few places).  Since this resulted in an inconsistent colored substrate (which would likely yield inferior results to his initial attempt), I then sealed this w/ Mp171  (dark gray epoxy)  then applied the MBC immediately (actually, I waited 2 hrs) over that.  I had considered mixing the gray & black epoxies, but the gray worked quite well on the wheel barrel, so I figured I was good to go.

So any variations in color are due to a combination of poor spray technique by me (although again, I'd like to point out that my results w/ a $100 gun were better than a pro w/ a $500 gun) and poor hiding capabilities of the MBC, as I was working over a uniform substrate & did the same # of coats over the entire car (4).  The other "boo-boos" are attributable to a combination of environment, incompetence and just misfortune.

So back to the original point - I think it's safe to say that  MBC does indeed cover poorly (or at least the RR1).  I will concede that it probably IS possible to get superlative results w/ it, however, due to my experiences, I would strongly recommend trying something else.

I used the single stage Omni urethane (MTK) on lesser visible areas on the Sublime '69 I am building (floorpans, inside the trunk, etc). I also did the insides of the doors in Omni EW1 white.
The green was pi$$ thin right out of the can, so thin I was scared to use the reducer. I added half the recommended reducer so it wouldn't be so thin. Coverage was extremely poor. Some areas got as much as 5 coats, and you can still see primer poking thru on raised ridged areas in spots. I used regular PPG DP epoxy primer mixed as a sealer before spraying, the light gray stuff.
Luckily, most of these areas get covered so you won't see a lot of it. The white covered a little better, and was a little thicker. But, NOTHING like Deltron, DuPont ChromaOne, etc.
Again, you get what you pay for in paint. I probably won't use the stuff again. 5 coats with some areas still not covered, vs 2 coats DONE with higher priced paint. The cost may very well balance out, you use less material with the higher priced stuff because it covers.

For primer, I did use a cheaper cost filler primer, Evercoat's Uro-Build. I thought this stuff worked great, & was very reasonably priced. It smelled, srpayed, filled, & sanded just like DuPont's Uro-Prime, but was half the price.
