First tried the foam brush on a very bad space shuttle playfield, find the method good for larger areas and for planking.
The red will need 2 coats, like wise the maroon. Yes you must sand between coats, I just use 800 wet and dry. I would normally use spot putty to fill up the scratches and heavy wear areas first, but this particular playfield would of been too hard/not worth the effort.
The black copyright and signature can still be seen and will be traced by hand. I don't like decals.
So you apply the paint to address the "planking" - but do you remove the excess with a rag ?
