I just did my first ever hand foiled plywood glass on fins. I used UV lam resin. I have been primarily using epoxy but wanted to experience using the UV (board is laminated using UV).
Tacked in place on bottom lam coat.
Saturated and placed 6 strands of fin rope on each side.
Wet out on wax paper two full 6oz patches over both sides of each fin.
UV Hot coat over all.
Im am obviously a novice to glass ons. They went on well - no bubbles. I possibly should have squeegeed more of the excess from the flats of the board adjacent to the fin so I would have less sanding to do (next time).
It looks like the area where the fin rope has dried against the fin joint radius and board flats has quite a bit of green tint. Is this caused by the fin rope (volan type treatment) or the extra volume/depth of lam resin which is greenish out of the can?
I dont mind that much but I want to do a leash loop (never done one before) on the deck and would like to try and get that clear. If its the fin rope - Im guessing I shoud strip out some strands from 6oz cloth and use those for the leash loop.
How many strands of 6oz will be appropriate for a leash loop.
Could be any of the above. Most likerly to be the UV catylist if you used that on the rope, if that was just on the hot coat then I'd say its the volume of resin, the rope could also give a similar efect if its become damp at any stage in its life, even if its dried out, as this effects the coating. If you handled it with bare hands it couls also just be grubby.
Not much help I know to be sure you'd need to do some tests, ie same rope dif resin/same resin and dif rope.
The colour is from not using catalyst and setting the fin rovings off in the sun. The resin will keep its original colour.
Try throwing a few drops of hardener in and it should go pretty clear. I f you want them completely clear dont put it in the sun and just shoot it with the correct amount of hardener.
