Cowling on the Starduster Too. I tried something new because I need extra strength here to hold the 1/32” balsa cowling when I start the engine. The inside of the cowl is coated with fiber cloth and epoxy. But after reading a link on planes built out of paper and alphatic resin mix, like paper mache, I mixed a slurry of wood glue and warm water and soaked my silkspan in it then draped the cowl. I have tear lines where I went over the nosebowl, which is what I want to make sure I get filled. I lightly sanded them and I can barely feel them now. Normally, I'd mix talc or microballoons in dope, give it a few coats and sand and you'd never know they are there. But I'm building this in my office and I absolutely cannot use dope here. I've never used auto primer before (well, on a model airplane anyway), but was thinking a few coats of high-build primer would get me there after sanding. I can spray that stuff outside and let leave the cowling in my car for a few hours until the smell is tolerable to bring back in the office. I will say that this cowling now is stronger than anything else I've ever built.
Anyone have any tips ??
Thanks
