I saw those cans when I stopped in there a couple weeks ago. They're mostly all modern colors. I picked up a couple cans of the equivalent to B7 so we'll see what they look like if I ever need them. Was hoping they'd have some engine colors but they did not.
That store is actually pretty cool. It's like a big version of what you'd see at a farmers market. Need a one time use giant socket? $5. Lots of good deals on cheap tools but there's a few head scratching prices in there as well. They have a ton of leftover paint cans for less than 50% of what you can pick them up at the big box stores for. Picked up some black appliance epoxy because it holds up better than Rustoleum. If you need smaller odds and ends, they have better prices than Harbor Freight.
