If that cowling is ABS plastic it won't take the heat when covering. If it's fiberglass it can be covered fairly easily with most films.. although it does take some experience, I've covered a few fiberglass cowls and components with films.. with great results. The films will adhere very well to a good smooth gel-coat. Fiberglass Specialties might have fiberglass components for the Kavalier, although I'm not real sure on it. If the covering won't work though, just paint it.

I do know they have a cowling for the Komander, as I just looked that up a few weeks ago. Someone left a whole Komander at the flying field on the picnic table where members sometimes leave and/or donate items they don't want... and this lonely, homely, kind of beat up Komander was just begging me to take it home. It was never flown judging by the incompleteness of it... but it was all there, to include the canopy, and the ABS cowl.. which was broken.. but after getting it home, and stripping the covering off(someones feeble attempt).. the bones of the plane look great... unbelievably well... as in whomever built it knew what they were doing. That Sig wood is some of the best balsa I've seen... They don't make kits like these any more... just good clean wood... that stand the test of it. It was pretty beat with hangar rash, but the landing gear was even there... rusted as it was. I was pretty jazzed, as we'd built one in the early 90's and put a nice .61 in it and it flew wonderfully. I think the airframe will clean up fine. I put it in my shed for a winter time project.. I just couldn't resist a free Komander!!!
