I have just attempted a coloured hot coat and the result looks shit house.
Short of re-shaping the same board again, im thinking about sanding the whole board back to the lam and re glassing with a pigment and just a single layer of glass each side
the board is quite light even when the filler had not been sanded,so weight is not going to be a factor i don’t think.
You have to do a baste coat with the colored resin first. Then you can color the hotcoat and sand and sand and it wont be splotchy. It will be one solid color.
You can also hotcoat it clear just as it is all crappy looking. Then sand it completely smooth and flat. Then come back and spray the board with acrylic paint and then rehotcoat. The trick is NO sand throughs when sanding the last hotcoat because you will notice where you tied to color match it.
Sanding down and reglassing wont do much than adding a basted color coat before a colored hot coat because the color is not gonna hit the foam. It will add more weight though.
its winter here and i don’t know if thats the problem or what, im using these powdered tints for the first time, and im disolving them and letting sit for half the day before using them,
but they seem to just separate from the resin when mixed with sanding resin, its reall frustrating the f@#k outof me.
some areas of the sanding coat were staying tacky as well ??? I have never had these drama’s before…
I am doing another board at thesame time and everything is going fine with it, only difference is im not using the flouro pigment on it, im using liquid pigment.
