[Shop-talk] Fiberglass front door

[John Mitchell]

    I have wood core, fiberglass covered front door, which I have used 
gel stain to give it a faux wood color and texture.  I've used every 
type of polyurethane, spar urethane, marine varnish, and nothing seems 
to hold up in the direct sun that hits it all day. It always seems to 
peel within 6 months or so.  I was thing of getting automotive 2 part 
urethane clear, or even mix up some clear epoxy resin to coat it.  
Anyone with any insight as to what would work in this situation?   
Thanks   John Mitchell     Shelton, CT
