RE: WarbirdColors Paint
One other comment about WBC. The paint likes a tooth to adhere to. Having a primer finish thats super smooth is the wrong way to go. Sand that coat with no more than 320 and even better if you can get away witn 240.
If the paints runs etc. you might have to thin a consistancy. Adjust the paint such that it flows from your spray equipment and no more. Three coats should be sufficient. I find the coverage decent. Yellow is always the exception!
