Can someone with good knowledge of fiberglass point me in the right direction of which type and resin is needed for the original waverunner's and wavejammers? currently working on an 88 jammer and 90 waverunner. Both have areas on bottom of hull that are scuffed and gouged down passed the gel coat but no cracks or holes. Can these hulls accept polyester resin? It is readily available near me for pretty reasonable. Epoxy resin seems to be hard to find near me and about 5X the cost.
