I have used the foam brush on my last two projects (latex over dope) with good results. The newest one is a Dynaflite Decathlon I have been flying since March of last year. The other is a 4 yr old Dynaflite Chipmunk I sold last December. Neither has had any paint chipping or any other paint issues. I am about to cover and paint a Sig 1/5 Cub and will be using this technique, as well.

In your experience with the latex paint chipping off, how was it applied? How much dope was underneath it? I am curious.
