Some Quick questions:
I normally put one hotcoat on the top and bottom.
Would a second coat be stronger?
Do pro glassers put a second coat on then sand off excess?
It’s really easy to get bits of weave showing on the rails sometimes.
Maybe just a second coat on the deck or the rails to keep weight down?
In most cases a second coat when painting is a must, does it apply here?
What’s the reccommened proccedure?
thanks
Bit of weave showing is fine.
No longterm strength in double hotcoats, as it gets brittle when fully cured, and the added weight just adds more ding to your dings.
But TOO THIN hotcoat means sanding off lots of cloth, so that's not strong either.
Rails need a bit more hotcoat resin, flats usually less. The way you brush it out usually takes care of that, more brushing in the flats, less in the rails that are convex.
…hello man, any hand lay up glassing schedule have 3 steps: stratification (lamination), hot coat (filler coat) and finish coat (gloss coat or speed finish coat)
right on, I just needed that little tid bit, I figured it did just wasn’t sure. I guess I’ll get some styrene monomer and put a second coat on next time, thanks!
You could do a rail and lap coat before doing a full hotcoat. Get the rails and laps and wait until the wax rises but before it hardens completly to add the full hot coat. Saves time and no sanding needed between coats. Plus makes a lighter baord than two coats.
