Rich,

Actually it really depends on how soon after the first coat of resin goes on that you apply the second coat. I still usually lightly scuff between coats but it is so easy to cut through the cloth that I don't get over enthusiastic. I have also just put the second coat on without scuffing and have never had a problem with delaminating. Now if you are using a waxed polyester resin......that's a different story.


And my routine is usually more like glass prime, sand, putty, sand, prime , putty, sand, prime, sand, putty some more, sand, prime......... then I paint!!! LOL
