Orange Peel in Epoxy

Hornetpilot · 10-21-2009, 07:24 PM

I put on two coats of SPI epoxy this afternoon. I was going to put on two coats of turbo 2K primer tomorrow, but I've got orange peel on a couple of panels. Should I block out the peel prior to the primer? If it needs to be sanded before the primer, what grit do you recommend?

Thanks again for all the help.

not really. the epoxy is for sealing and adhesion . i would just continue with the turbo primer.

If you apply your 2k primer after the epoxy has gassed out, you will need to give the primer a 'tooth' to bond to the epoxy with and you can achive that by sanding and what grit all depends on your film build. If its a small build, I'd use 220g, a heavier build, 180g that way you dont ruin your epoxy or body work.

OK. Many thanks, fellas. I'll spray the primer tomorrow.

you have 7 days with spi to top coat or prime without sanding. ragtop's right. if you go past the window scuff with 180 .
