RE: Demon cowl, take 2
Yeah I needed to spray it, for a production mold the surface finish has to be glass smooth or as close to that as you can get. I never got a finish I was happy with by brushing.
I believe the residual solvents in the plug finish affected the wax, and when I thought I was building successive layers I was probably removing most of the wax again. So in other words, I was asking for trouble. If I had a working air brush at the time I would have sprayed a proper finish on the plug itself not to mention the release coats. Then I would not have had that problem or so the theory goes. But as it was I decided to have a go with aerosols. Duh. Just get the right tools silly..
