Maybe the dip spray is kind of like spray-foam and it needs to cure over a few hours, so you could only do 1 side at a time... Still doesn't work when it's a round object, like the pvc pipe/wooden dowel.
Gesso is awsome though~ ^^
This is making me wanna touch up my keyblade but the original paint on it is like some weird metallic sparkly stuff. Like, seriously, sparkles are in it. I tried to touch it up with plain metallic and it shows in some lighting as spots on it, but in other lights it blends right in >:
