My plug is done and I'm about ready to lay up a mold. This will be used for prepreg so I'm using premium resin tech rdr-1902 high temp surface coat and rdr-3212 resin. I have some concerns with the surface coat. It's a bit thicker than I imagined but I guess that's good so it won't run, however after mixing a small test batch, it seems pretty slow to release air bubbles. As you can see in the pic of my plug, there are areas with vertical walls and even a few areas of negative angle. For air to release from the surface coat as I brush it on, these bubbles need to rise to the surface to pop right? So any areas that are beyond vertical with a negative angle, I would think are gonna have a hard time releasing air. I picture a bubble just rising up against the surface of the plug and staying there. I'm wondering if I should apply the surface coat in partial areas with the plug oriented so surface coat I'm applying is face up, allowing better release of air bubbles.  Do I need to bother? Or can I just brush it on the whole thing as it sits in the pic? Looks like pics got rotated 90 degrees, the pointed nose is up
