Actually you cant get much cheaper. For White or black, the 15oz can of 2x is 5bucks at Home Depot! I don’t know what you call a light coat, but to me a coat of paint is a complete wetting of the surface. The 2x coverage allows good coverage with a misted tack coat and one full coat.to me this is what I buy when I want a cheap ‘glue job’. Lol. Krylon is thinner and atomizes very well for a nice light coat.
