I powdercoat a lot of little parts but the block wouldn't fit, and it's way way too heavy for the racks. Powder for the most part looks just like paint, its just 10 times more durable. I really wish I had a bigger oven but its pretty costly compared to my $50 craigslist oven. I can't even fit a wheel bigger than a 15" in it, and 15's won't even fit over my brakes lol.
