I found this place after searching for a local source for resin. I found the staff to be helpful and accommodating both on the phone and in person. I purchased 10 gallons of the 4117 laminating resin. I have used this product and it has exceeded my expectations. I use the resin for boat rebuilding. I have used it on 1708, csm, and as filler. I will return for more when I run out. As far as costs go, they are more expensive than the online outfits, but you don't have to pay for shipping or hazmat so It's a wash.
