You'd be better off taking your trim off, doing some prep work and have MAACO paint it.
To do it yourself, single stage, will still run you $300-500 in supplies. If you have never painted a car, or used a gun then it will end badly, I've been there.
Do the prep, and MAACO can give you a decent single stage for the same price or a 2 stage job for ~$1,500 and you'll be a lot happier.
It's a myth that single stage is easier, it's not, people are just intimidated by clear coat. Granted a non metallic single stage isn't the most difficult job in the world, but a metallic single stage is a royal pain in the ass for a beginner. I find 2 stage painting easier, just more time consuming.
It's also next to impossible for the garage painter to create a dust free environment, it takes a ton of plastic and a few fans to create a side draft paint booth. Trust me, just spend $500.00 with MAACO if your just looking for a decent paint job.
