The best way to go (for me and it works) it to put a layer of catalyzed gel coat down on to the MDF and wait for it to cure, then rub it down so you have a nice smooth gel coat surface. Make sure you work your way through the grits ending up with 2000 grit wet and dry, then polish with cutting compound. Then do 6 coats of release agent leaving 15 minutes between each Coat. you shouldn't have any more problems. Let us know how you get on! Shane -Carbon Amateur- Never give up! Tags Gel Coat MDF

I second that! or use a coat of pigmented epoxy on top, the mdf will suck up some of the resin and saturate, then you can sand and polish and work on a nice surface Matthieu Libeert Founder MAT2 Composites X Sports website: www.mat2composites.com
