Primer Help

[billfury]

Need some help from the paint experts please? I'm switching paint guy's do to the first one's life got in the way. I found another guy who I seen some of his work seems to be perfect. My car is now in epoxy primer sealer painted by the first guy. I showed the car to the 2nd guy and he said for me to sand it all down because I should have used etching primer. I thought the epoxy primer sealer was better. Someone please clarify this for me. I tried to read other post about this and it's confusing. I'm not selling the car so I'm not looking to take any short cuts. Thanks.

Find a new guy, epoxy is fine. Did my whole exterior with Eastwood's and topped it with cheap Kirker pure white. 2 years and it's fine. (Unless it's sat out in the sun and rain for long periods, epoxies have no UV tolerances.)

Hi,

I think painters tend to stay with what they have long term experience with. Remember, if a paint job goes bad, they get the blame and may have to do it over again. I suspect the second painter has used etch primer for long time and knows it works. He may also not have experience with epoxy primers. Many collision shops use etch primer because it allows a faster process. Time is money when the insurance company is already trying to cut costs.

Neal is right on when he says there is nothing wrong with epoxy primers. When a car is restored we are not concerned about how long it takes as much as how well will it hold up long term. Epoxy primers are very tough and I think today are  the way to go for restoration work.

If the epoxy primer on the car is in good condition, you would scuff it up to get mechanical adhesion and spray on a fresh coat of epoxy. Then within the recoat time for that brand of epoxy primer follow with your next coat of 2K build primer-surfacer. Putting on the 2K primer-surfacer on the fresh epoxy allows a chemical bonding to take place.

Thanks guys.

Epoxy primer is great!

As already mentioned- your new painter is going to be hesistant to warranty any work he does because he did not prepare the metal for topcoats. He is justified, so it's really up to you.

I prefer to use both, the Self Etch Wash Primer, then the Epoxy Primer. I know most others do not do it this way & all a matter of Opinion. Some just prefer epoxy. As far as I know either way will work fine & I've done it both ways.  LEON.

I use Epoxy over bare metal and never had a problem... In fact I think it's over rated I saw a old Duster I had painted about 13 years ago and I used laquer primer over some bare metal and the paint job still looked as good as the day I sprayed it....
