No. For example, only certain epoxies will cure properly in the presence of water or at low temperatures. For in-the-field repairs polyester cannot replace the proper epoxy. If you must laminate to white oak, polyester just won't cut it. If you wnat a good colour match on a polyester boat, epoxy won't cut it unless you paint it. The bond between polyester and epoxy vaires with the type used. Best to use epoxy for all repairs on epoxy boats to be safe. >By epoxies I'm assuming items >under the West or MAS labels, right? West, East, MAS, System Three, Fiber-Glass- Evercoat, etc formulate epoxies. Most work fine if you follow the directions. Mosty boat builders go straight to the manufacturers (Ashland, Reichold, Ciba-Geigy etc.) for products tailored to suit their needs. Will standard gel coat adhere to an >epoxy based repair as well as a polyester based repair? Far better to use polyester throughout to assure no problems. Mixing and matching can cause problems that the pros know how to avoid.
