I have been using a decent grade of polyester resin from http://www.FGCI.com for all my engine room repairs and still have five gallons left. I know that its not an adhesive, where epoxy is and I would prefer to use epoxy on this project, however I'd rather not spend the additional money if the polyester resin will work. Additionally I have been using a product called ATPRIME between the old lamination and the new.
Here's how the manufacturer describes the product:
ATPRIME® 2 is a two-component urethane-based primer system developed to enhance adhesion to FRP in secondary laminating operations, including bonding to non-air- inhibited surfaces. The material is applied with a brush or roller to prepared surfaces. Bonding is formed chemically.
ATPRIME® 2 significantly improves interlaminar bond strength when used with Atlac® and Dion® resins. It will also enhance bonding of FRP to concrete, bright carbon steel, and thermoplastics such as PVC.
My question is, although the polyester resin is not the best product for the job but will polyester resin make an acceptable repair?
