Eastwood epoxy primer

I have noticed there is a lot of difference in Epoxy primers, some sand good at right time, others not so much. My opinion is expoxy primer is meant to give a good surface, specially on bare metal, for further work, as in a high build primer, then on ward. Let me say this, always look up the tech sheet on what you are using. It will tell everything.
I love SPI epoxy but when you read the sheet there are a lot of dos and don't and they can all it you in the ***!! if you don't know
Surely Eastwood has available a tech sheet for their epoxy. Eastwood sells good product but they buy the stuff from someone.

Totally agree. I wouldn’t use an epoxy primer in place of a “sanding” primer. Or a sanding or high build primer in place of epoxy. But I have sanded epoxy primers and they are not “one and done”. I just wanted to say that epoxy primers can in fact be sanded, and they can.

Typically we would shoot an epoxy primer on the completion of bodywork to seal everything, including the bare metal, and then shoot a sanding primer over it. Both to use it as a guide and to make the next round of sanding easier. But sometimes we had our rose colored glasses on when we decided it was time to shoot epoxy, so further work was needed and sanding the epoxy coat was necessary. It’s not as nice as primers that are meant to be sanded but it’s by no means impossible.

And absolutely follow the tech sheet for the paint you’re using, that should go without saying.
