Ok so I've been trying to get into this for long time. Been doing swirl dips for a while now and ready to do some film. A lot changed since first time I started researching all this. I want to do a few basic dips. Before I go full blown spending 100s. So question is what's a decent priced activator spray and good place to get decent roll of film. Not interested in 12 inch sample packs. Also is self etching primer my best bet before base coat. And what's recommended for base coat enamel, regular does it matter??
