ORIGINAL: Rubbernecker Not trying to be a know it all but will give you 2 recommendations: 1. Skyloft requires an enormous amout of filler. I used about 8 coats of dope to seal and it still had some pin holes. That weave has openings the size of #2 pencil lead. Silk or polyspan in my opinion are much easier. 2. I wouldn't use drywall stuff. What ever goes on the skyloft (silk and polyspan as well) needs to be flexable? Ask me how I know?[&o] Found out the hard way using Dupont 30 S primer with a flex agent on Skyloft. Painted it with epoxy paint and after about 10 flights, the covering started cracking very bad. Wound up pulling it all off and Monokoting. Good luck, John Remember, there is a reason Skyloft is so cheap!
John, I gather that opinions differ, some folks have better luck with it than others. I thought I'd try a test case with PVA primer, because it is water based and an acrylic product, which I believe is more flexible than the standard automotive paints, and should fill with less coats.
Thanks though for the warning note. I found out a silk supplier through the Ringmaster Brotherhood. I've used silk and am quite happy with it. Usually weave was filled with 3 or 4 coats of clear dope. One can put a lighter weight finish lighter than plastic iron ons, which is also very strong and resilient compared with silkspan and attractive, too.
It's just that this hobby has over time become more expensive with the decline in widespread marketing that used to occur when many people participated and there was a local hobby shop within arm's reach.
I'm just trying to have the most bang for the buck. So, I'll pass on a report as to my success or failure with Skyloft.
