Need to do some glass and gel coat work. In my experience, using west system epoxy or any for that matter cures with a yellowish color when dry. When you try using gelcoat, I find it is difficult to not have the color show through the gelcoat. I thought of using white pigment in the epoxy mixture to minimize this--does anyone know if this weakens the glass and have any other ideas? <br> <br>Also, if I want to make a gelcoat paste for fixing small scratches and imperfections, what should be used to thicken the gelcoat. I've thought of using collida Silicone but find it discolors more quickly. Any thoughts? <br> <br>Don S. <br><br><br>
