I'll second the suggestion to go to the auto paint shop of your choice and shop their selection. (This very nearly same question came up on Velocipede Salon and I gave that same answer). When you're starting out there's all kinds of questions that you'll have and the local shop is the best place to get those basic answers from. Also they might be able to provide you with less the complete retail package amounts of some of the chemicals, like activator, reducer, accelerator. Or be able to point you in the direction of a friendly local painter (likely of cars) that can sell stuff on the side. With some companies you have to buy a large quality (gallon/quart) of product that each time you paint you'll only use an ounce or so of. Make sure you get all the initial tools from them too. Just like you were starting out in cycling Andy.
