| My next video. www.youtube.com Information and a demonstration of how I layup one of my molds. Headlight eyelids. Big thanks to Randy Roach(GlasserGlass) for some handy tips and some inspiration to make a vid or two. EDIT(30/May/08): I noticed this video has got 7000 views in 2 months so it looks like ill do another one for you all. Considering how many people are viewing this video I thought I would clear up any misunderstanding and give allot more text info here relating to the video. I only put one wax application on this mold because its an older mold and its been well used. For fresh molds you must put several layers of wax on and I would consider PVA as well if the mold is less then a week old. Always use PVA (or equivalent) on your plug surface before molding. Ive got allot of PMs about the gun. The gun used in this video is just a very cheap method of spraying gelcoat on some of my smaller molds. For the larger parts, tooling gelcoat or for anything I want precision, I use a HLVP gun with a 3.5mm tip. Most of the time for these small parts I just brush gelcoats, you can get just as good results. When brushing leave longer then usual before resin/CSM, I usually leave it overnight. This is so that any high spots from the bristle streaks have time to fully cure. If you layup over any wet gelcoat you will get alligatoring(crocodiling) reactions on the surface. There is no maximuim time between gelcoat and resin/CSM. Gelcoats do not contain wax which means they will ... |
