Thread: finally under primer need advice (pics)

Epoxy isn't very good for finishing the surface for paint. I would shoot at least two coats of urethane primer imidiately after the epoxy, then dust it with a guide coat for your block sanding. If you wait too long you will have to sand the epoxy before repriming.

really .. I was told the the spi epoxy is great and is also a high build primer , it covers 80 scratches in 2-3 coats... that is what the persone I talked to when I bought it told me. then I was told by spi to wet sand with 400 then reduce the epoxy by 25% shoot one coat as a sealer wait about an hour shoot base was I told wrong by spi?

thanks,

I should qualify my answers.

I have no experience with SPI products. I would listen to them first, or someone who uses their paint daily.

My only experience with epoxy primer is PPG. From everything I have heard, it's used for it's good adhesion, and ability to seal out moisture. If the SPI is formulated in a way to provide those things, ...and can also be used as a "primer/filler", good for them.
