linda20003 I find there’s issues with adhesive spray or even contact cement. If it gets too hot from temperature swings or even the torch when applying resin, it can bubble and come off.
GinitaXOXO there’s a couple options for supplies. I usually go to Curry’s for in store purchases (I find some ink, Yupo, they sometimes have acrylic, they have panels) or once in a while I go to Michaels and abuse those coupons haha. Otherwise, most of the stuff is done online
You can use gloss medium to seal the panel. This is recommended by Golden for preventing SID (support induced coloration). I’ve also been taught to apply the gloss medium over the entire panel, front and back. This helps prevent moisture from entering the wood and making it swell.
