When I bought a can of crystal clear Lustrekote from tower it came out to be white! It turned out to be mislabeled. And the white isn't even glossy. I have about 5 cans of Lustrekote and they all should be glossy but they are not. Even when topped of with crystal clear glossy it still looked and felt flat. I now clear coat using a paint called "Varathane" clear finish. It says on the back that its mainly used for clearcoating the insides of furnitures. The clearcoating is amazing and it hardens the covering a bit and it feels and looks like glass. Now thats what I call glossy.

For decals so they wont come off, I use Monokote clear if its not painted. If it is, I clearcoat it using Varathane paint. Btw, I used varathane because at the time thats the only paint I had lol. Works Great though.
