When painting a soft plastic bait there are not to many choices for paint and only one company that makes it. That company is Spikeit, they have two types one solvent based and one water based. The solvent one smell really bad and caution when using it should be a top concern. The water based one is great but take awhile to dry(unless you force it to dry with a hairdryer or heat gun).This one does need to be top coated with a solvent based clear or dipped in Plastic to seal it. It does dry but if stored touching each other they will stick to each other. As for making a hollow body swimbait I have a video on you tube that shows me making one and painting it too, look up Franksrooty2 and look for the one you want. I know it does not show how to get it off but you just slide it off.
