OK, this is proof that I am not afraid to share my failures! Look at my radiator apron!!! This is epoxy primer over sanded Urethane Enamel. I thought that you could use epoxy primer as a sealer. I guess not!

In sharing this I want to let those who might be afraid of doing their own painting know that even disasters like this are not fatal. I'll just take it back down to bare metal (which I should have done in the first place) and do it again.

PPG DPLFxx epoxy primer is also used as a sealer. PPG recommends that more reducer be used when it is sprayed as a sealer. The epoxy primer shouldn't have caused the alligatoring. I have never had this happen and I have painted two model A's using a lot of PPG epoxy primer along the way.

This is not PPG epoxy primer, but EP by Eastwood. I guess all epoxy primers are not the same!
 
Painting is obviously not your game ! I tell people that an engineer should not practice law and I promise never to build a bridge! It's a good thing it was paint you were playing with and not dynamite ! Wayne
 
It is always best to use the same company for all the paint products going on your car. Shopping for price does not always give the best results. It is also very important to follow the directions for mixing and application very closely.
 
Friend, Bill, did his horn BEAUTIFUL, tied it in a plastic bag, on the wall & 3 years later, it looked like this all over!

It's the same effect when you try to paint lacquer over enamel. I've made that mistake in the past and will not again.

You never want to cover a freshly painted car or parts with plastic. The paint thinners escape for quite a while during the drying process. Not just a week or so but a month or more. We used to pull a car out of the booth that was was painted with the state of the art urethane at the time(late 80's to the mid 90's German urethane) and we would cover it with lightweight painters plastic to keep it from getting dirty from the other activity going on in the shop. Little blisters would appear a few days later. It took us a while to figure out the cause. The plastic was just draped over the car with plenty of air flow circulation so we thought as it would flutter when air blew through the shop from the open doors...wrong! A hard lesson learned. These were mostly Mercedes and BMW's. Lots of spendy re do's. Now, I never cover anything after its painted with anything for a long time after. No more little blisters.If it gets dirty while waiting to re assemble so be it.I just wash it carefully as to not scratch it.
