After stepping into the clearcoating/painting business I can tell you, with or without a paint both it is a total PITA. I cant stand clear coating a part after de moulding, then the clearcoat gets wavy or a bug in it. then i san and polish, still not perfect. I'm starting to learn this real fast; the key to a perfect part, is taking a mould from a perfect part and polishing it there. I plan to make some really perfect molds, then try this. The site says you can brush it on, we for my size parts that would be really connivent. Now matter what the surface of the part will be perfect but if your paint strokes on the back are to thick you may see your weave get a little wobbly. When making parts smaller than ".5 meter" I think my cup gun is a bit much? think an air brush system would work? If Brute Force Isn''''t working your not using enough...

I was thinking much thinner, then kinda kept trying to ad a lil more add a lil more and I ended up building the speckles up. I'm just gonna Jam it on thier quick. How many passed to you typically do over the same spot? Just one? 1.5? I am thinking that Laying down the GC50 is even trickier when working with small parts under 1ft by 1ft. I will be back with pics' If Brute Force Isn''''t working your not using enough... Edited 13 Years Ago by Carbon Tuner
