Default RE: AR-6 Wing mold construction

Well, I am sorry to hear that Kevin. I used the mold sealer, followed by the release (3 coats of each, 10 minutes apart and wiping off before it dries) and it worked flawlessly for me. I know It only has a 6 month (or less, if you don't keep it airtight and room temperature) shelf life once opened. You also have to use a catalyzed 2K paint (I used an AU automotive from Napa) for best results. I know some resins & paints have compatibility issues with certain releases, so that might have been what happened to you. []

I did some sample lay ups prior to risking my plugs, so I was sure it would work with my components. I also laid up some flat panels (identical to the mold surface) so that I can test paint/resin compatibility prior to putting it into my molds. I broke my last quickie fuselage mold by using a resin/paint combination that went thru Partall #2 wax & PVA #10. [:@]
