it dries crazy fast and i've found it to be quite durable as well. i've not used the eastwood version so i can't comment to that, but i've been using seymour stuff for years and always been pleased.
First, I must apologize. The Eastwood equivalent is called Spray Gray. You'd think I'd know. I bought several cans when it was on sale many years ago.
I used to buy a lot of stuff from Eastwood. Their prices were reasonable, and shipping was average. In fact, I bought my first cheap powder coating gun from them about 20 years ago, and until about a year ago, I bought all of my powder paint from them. Between about 2020 and 2023, the price of their powder paint AND their shipping went up drastically. In fact, I now buy all of my powder from Prismatic. They sell to professionals and have a LOT more colors. Plus, their prices are about 40% cheaper than Eastwood and their shipping is half as much. Their high gloss clear powder is almost twice as expensive as the Prismatic clear. In fact, a 12-ounce spray can of their spray gray is $21. That is higher than pretty much any other brand. I haven't bought much of anything from them in the past year.
