do I need sealer???

The tech sheet for Dupont Nason Full-Base Basecoat says "SEALER (Required)" and lists a couple of there sealers you can use. The salesman at NAPA said I don't need it unless I'm painting over old paint. I want to paint over epoxy primer over metal. The fact that the tech sheet says "SEALER Required" scares the heck out of me as I'm trying to only do this once. Who do I believe??? What do you experts say???

As long as you don't have any bare metal or "bondo" showing you don't need the sealer. But if either of the two are showing you will need to seal them. Nason may have adhesion problems on the bare metal. And the "bondo" may bleed through the base coat.

So if you have a solid surface of Epoxy you will be alright.

I usually seal everything with Epoxy that has been reduced and apply my base coat in approx one hour later over the reduced Epoxy/sealer. Makes good for adhesion purposes.

Required sealer

Hi daoldbuick ,
I agree with Countilaw, in that if your epoxy surface is sound/solid you will probably be o.k. ,as epoxy is basically a sealer in itself. However, the paint you are using may need sealer for proper color holdout .If you have any primer spots, paint overspray(maybe from painting jambs),spots where the epoxy is maybe a different color due to sand throughs, slightly off mixing ratios(hey,it happens),or several other factors, your topcoat paint color can often be GREATLY affected . Nason paints are a budget version of DuPont paint , and the color may not 'hide' as well as more expensive paints do. In my past PROFESSIONAL experience ,if the sealer color is not of one SOLID color,you may be able to see through the paint at any possible surface color variations . This would result in having to put on several more coats of basecoat than is either recommended, or, needed just to hide the variations .If your epoxy is all one color, I'd go for it ! If not, I'd use the sealer, it is WAAAYYY cheaper than more paint & especially if the paint says sealer is recommended .
Just my $.02 worth, GOOD LUCK , Rick

Thanks Guys. I'll just paint over the epoxy then. The guy that sold me the paint was supposed to know what he was talking about but now that I have a second/third opinion I can proceed with more confidence. I'm hoping to paint the dash, firewall, door jams, etc. this weekend. Thanks again.
