Uses for SPI Epoxy:
SPI Epoxy is one of the finest available and it’s great for use on any type of metal or aluminum if properly sanded and cleaned. This epoxy eliminates the need for an acid- etch primer. Use this epoxy on bare fiberglass or SMC before applying body fillers or 2K primers for best long-term results. |
OK, I am going to ask Barry, the owner of SPI. Will let you know what he says.
I think you are confusing self-etch with acid-etch. They are different as near as I can tell but I am far from an expert.
