you can buy really small quantities of the envirotex .... I think the cheapest kit at Micheals or whatever arts and crafts store .. or even amazon for that matter is roughly 15 to 20 bucks .... and you can do several pedals with the amount in the kit .... as far as decals ... you got to try different brands ... I've run into some horrible ones ... and I've run into good ones .... right now I'm using pretty old ones that I scored from some woman at work , but they are thick and stand up to the heat well .. then it's just simply practice .... I'd be lying if I said I didn't have about $ 100 worth or so of enclosures I've got in a box from " testing " that didn't make it through my quality control OCD vision
