what are the affects of air brush on the bond of foam and resin? where do you put decals (on the foam, between glass layers)? what kinda ink would one use on rice paper, where does it go in the layup, can it go the whole length of a board, affects on bond? thanks

In other words the resin is getting down into all the little holes, nooks and crannys in the foam then hardening and drying in a state of a death grip. As far as your airbrush goes your pressure in your airbrush is blowing paint down into all those nooks and crannys also. Thats why it takes many passes of the airbrush to get a good solid color. Spraying at various angles also helps. After painting all those nooks and crannys are still there so your resin will still be able to lock into them. Air drying with a fan set on low is the best way for drying paint, stay away from blow driers. As far as laminates go, your top laminate should go between your two layers of cloth. On the bottom they go on the foam with your single layer of cloth on top. Remember your laminates go in at the same time your laying up your cloth. Have fun. And yes you can put them anywhere.
I make styropoxy boards with lots of glass layers, so sequence is critical in laying up logos. If you are putting the logo in an area with two or more glass layers, do this little trick. Cut out all the glass in place. Lay back the top layer past the proposed logo location. pull the logo out of its protective location and place it at arms length. Get your tools and protective devices in place, then mix all the resin. Cover the glass below the proposed logo with resin, then apply the logo. Then unfold the top glass layer into place over the logo. Continue applying resin. This process ensures that the glass under the logo saturates with resin. There are so many parts of this sequence, it’s easy for us amateurs to leave one out. You might want to make a dry run (without resin) before laminating. Correcting mistakes steals working time. Unless you are using Suncure lam resin, the mix could go off before you’re ready.
