RE: Painting SIG Koverall
I always use Dupli-Color High Fill primer after filling the weave. As far a paint goes I use latex sprayed thru a HVLP gun.
As far as painting goes it takes 3-4 coats of sprayed paint no matter what kind of paint you use.
The latex holds up well to gas but you must fuel proof it when using Nitro.
Here are a few planes that used the Dupli-Color and latex.
