I’ve used the CA from Bob Smith Industries for several years now. It’s by for the best that I’ve ever used and can be found in several difference thicknesses. I always apply mine with a tooth pick but I’m fairly certain you can get an applicator for it… or I’ve seen some packaging versions of it with them as well.
Can’t say to whether Hobby Lobby has it as I’ve not been to one in quite some time but I know Hobby Town USA does. I get mine off Amazon.
