Teardrops n Tiny Travel Trailers

Ok, I come again to this wonderful forum with my silly questions. Thanks in advance to all who reply.

I started out using West Epoxy for my woody project. I mainly used it for wood encapsulation purposes. Recently I was given 2 brand new gallons of MAS Epoxy and hardner (enough to cover the "Rose" nicely) and my question is this:

Are there any known compatibility issue between different types of epoxy when placed over top of each other? Of course the first (bottom) coating is completely cured.

I have contacted both manufacturers and their only response has been they can't say (probably because of liability, etc.) Has anyone ever experienced such a situation?

no problem. before 24 hours, bond is more chemical and better.. after it fully cures, rough it up and you get a mechanical bond...... be sure to sand it.

...yep just sand it, clean the sanding dust of with a rag dampened with de-natured alcohol (or solvent of choice) and apply new epoxy...it should be fine with proper surface prep.........

Yep...I've used West, MAS, and Raka in different circumstances in a cured state. Just let it cure, sand, clean and move on!!!!

Maybe it's worth adding - never try to mix resins or hardeners from different companies - company B's hardener is unlikely to set off company A's resin.

Yeah, I know you would never try this - but someone else might!
