Polyester resin over polyurethane enamel

Question for the paint and resin experts???

I am rehabbing my 25 Terry Jason lobster boat.

The helm dash is reconfigured and I have a combination of "new raw plywood and the original plywood which is covered in poly ester resin, mat with a finish coat of Petit Easypoxy polyurthene enamel topside paint.

I have the paint sanded pretty good with 60 grit paper, scuffed up real good.

I want to re-cover the whole dash with a new layer of mat and then maybe gel coat.

My question is will polyester or vinyl ester resin "stick/cure" OK to the sanded scuffed polyurethane enamel paint??

Appreciated, Bill D

 

Was the PU paint 1 or 2-pack ?

 

one part

 

Odds are it will be attacked by the resin. If it is one-pack, paint stripper will remove it fairly easily, which is probably the best plan if it isn't too big an area. You could always do a small trial area and see if you can get away with it, but it wouldn't be in the textbook list of methods.

 

You cannot use PE or VE resin over paint.
