Just finished skinning my SOF kayak with 9 ounce nylon. Have Cory’s Goop polyurethane to apply and want to keep the skin white (on my last one I used rare earth powder pigments and it came out fine, but I do like the look of white better). Have been advised that tinting the goop with titanium dioxide powder will work. Does anyone have any experience with this or other ways to get a decent white tint for two part polyurethane? Am I asking for trouble with a white SOF in terms of longer-term discolouration? Thanks for any thoughts/advice/tips on this.
