True, but Poly Fiber often has a urethane top coat, so you still need to know what's on top before you spray it.

If the rash isn't too bad, you might be able to touch it up with a brush and unthinned or minimally thinned paint. If it's urethane, there's really no good way to make an invisible repair without painting the entire surface. If it's not a show plane though, you can make it good enough. One way is to "back mask" the area to be painted. On each side of the repair area, cover THE REPAIR AREA with masking paper and tape the edge. Then fold (but don't crease) the masking paper away from the repair area so that instead of a hard line , your mask line is curved away from the surface. This will make a soft feathered edge around the area.
