It is Tremclad paint,I started with 75 % paint poured into a pickle jar 25% mineral spirits with a couple of ounces of pentrol on top.ButI did add more mineral spirits to the jar after my first panel to guarantee it flows may be 30% to 35% hard to say. Its all trial and error .
And all of it foam brush only {sitting flat}
You can see my bad body work skills on the door PIC ,
I have very little orange peel ,this method does put lot of paint down you get complete coverage after two coats cant wait to see what 6 coatslooks like.
