I have sprayed Nason Single Stage Urethane Bahama Yellow a couple of times. Price should be right in line with the TCP Global stuff and you will get the actual color you want. Absolutely no need for base clear if you are looking to save money. If you want a little added depth of shine/gloss, you can use some integrated clear in the final coat but bear in mind, it will not look correct then as it will be a little too glossy versus the factory paint
