RE: Composite ARF Impact
Primer is not necessary on the glass fuselages for paint adhesion. As long as the surface, whether glass or gelcoated or pre-primed is scuffed for the paint to grab onto, it'll be fine.....The purpose of primer on the glass fuselages is to high light pinholes and any flaws. Once perfect, the primer can be sanded completley off, however, that may cause more pinholes if you sand into the glass...so, it's better to leave a little primer on so the surface looks translucent and paint......The pre-primed or the gel-coated fuses eliminate a lot of the pinholes and save about two shots of primer, cleaning the gun and sanding. One can even add Monokote (the regular iron-on version attached with the Windex method) as trim, lightly scuff and clear if needed.
I'm curious about this plane's performance.....I'm looking at it too.
Soon to move to Vegas
