anybody have any experience with a certain brand of epoxy primer under polly primer?

was planning on using the PPG epoxy but was told that i could run into problems if i didn't use an etching primer before the epoxy

what epoxy primers do you use?? (i plan on using featherfill g2 over it )

 

You aren't supposed to put epoxy over etch. At least, I've always been told that is a big no no. Epoxy primer forms a mechanical bond directly to the substrate and does not require an etch primer.

I have used kirker epoxy primer and I love the stuff. Unlike other epoxies, it sands very easy and is rather cheap.

I have also heard great things about SPI (southern polyurethane) epoxy primer. They'll answer any questions you have about their products via email or phone and their p-sheets are great.

Featherfill will be fine to go over epoxy.

 

who told you that you would run into problems if u didnt put self etching first? they were an idiot

u can use self etching, be4 i use a regular primer surfacer....
or u can find a sandable epoxy primer that is like a surfacer, with the epoxy protection

 

what i was told was that if I plan on using PPG epoxy primer i would have to use an etching primer first then spray ppg epoxy i dnot know will probably give spi a call i was just trying to stay within the same brand to make sure everything is compatible
