Can you layer epoxy of different brands?

I have the first coat of epoxy down on the deck interior of a Pertrel SG, and want to apply a fill coat inside of 72 hours from initial application.

I'm using CLC-supplied MAS epoxy and am short on hardener -- I'm not sure I have enough remaining for a fill coat. I live on the west coast, where MAS is hard to come by. This is the land of System 3, and I cannot get a resupply of MAS inside of 7-10 days.

Question to you is whether I can use System 3 for the fill coat? Both epoxies are 2:1, and know not to mix and match resins and hardeners between them, but is it viable to layer one over the other?

If not, I'll have to await a resupply and sand between coats.

Thanks in advance...

Lots if epoxy info.

Any epoxy (not polyester) will stick to cured epoxy if it is sanded.
