.035 size. This large is hard to find and matches a lot of the OLD SCHOOL marine flake! Note on flake sizing. 0.015 can be sprayed out of most 1.7 tip spray guns, 0.025 a 2.0, and for 0.035 you will need to use a dry flake gun, cheese shaker (if a smaller project), or a large tipped gun such as a 2.5 to a 3.0 if available.
