Here is what I did:
-Cut 3 pieces of exterior grade A-C plywood to fit my transom.
-Sanded.
-Wiped down with acetone (could not find styrene anywhere).
-Applied polyester resin on once side of first piece.
-Layed mat and added more resin (wetted out mat completely).
-Applied polyester resin to one side of next piece.
-Layed that one on top of first.
-Repeated etc. to get plywood-resin-mat-resin-plywood-resin-mat-resin-plywood sandwich.
-I clamped the crap out of it and let it cure for about 2 weeks.
I removed the clamps yesturday and I noticed that today the edges are separating.
I have read the whole epoxy/polyester debate so please dont go there...
What did I do wrong? Not enough resin? Improper prep etc?
How can I fix it? Can I just add resin to where it is separating and re-clamp or do I need ot start over?
