I am having several issues using your epoxy coating resin as a top coat over a laminate  composite layup consisting of wood and glass fibre. The outer layer of the layup is .6mm veneer which has a thin coat of infusion resin applied to it at the layup stage in order to give an even colour when the laminate comes out of the press. (previously some infusion resin had soaked through the veneer and given a patchy look to the outer surface even after the coating resin had been applied.

Hi Ben,

Again, that's useful feedback. A customer (a professional sprayer) told me a story yesterday, I don't know how true it is, that a Bentley that another company had sprayed (and £30,000 paint job) had come in to him to be re-sprayed after the paint finish was unacceptable. The previous sprayers had battled with fish-eyeing and the repair work they did was visible in the paintwork so it all had to be done again. The problem was finally traced to a can of 'Pledge' furniture polish that has been used inside the car (but inside the workshop) which contains silicone. The silicone particles in the air caused the paint to fish-eye and cost the company the £30,000. If you've used that microfibre for anything along the lines of polishing in the past then it might well be the cause. Also, wet sanding when resin is only partially cured could well be another problem. If you'r insure, but the part somewhere really warm (40'C) to cure off fully before wet sanding.

I hope it starts to come good for you.
