Best softwood species to glass over
Making a crowned pilot roof cross beam, 1.5" wide by 1.8 high with 4" crown over 7'. What is a good wood species which will work well with poly resin and fiberglass? No loads above the roof, just want the resin to bond well. So strength not an issue, just bonding adhesion as poly is poor at that. Thinking of soft wood for weight, cost, and ease of working issues.
Thinking of pine, spruce, or east. fir/hem. Will shape, sand with 60 grit before a saturation coat of laminating resin (thinned with 5% styrene) and fabric.
