OK, got all the old silkspan off the open bays, I want to do transparent yellow MonoKote to save time and a little weight. The silkspan was dyed yellow so the stuff left on the leading and trailing edges is not noticeable under the film. This dope is butyrate, over a year old. I have sanded the surface, and it seems to try to get back to bare wood will mean really getting aggressive with very course sandpaper. I'm still working out of a bedroom, so this is not the best option.
I was thinking I could sand it smooth with say 220 and after tack ragging it off just apply the film over the old doped structure. Anyone done this? Since this is electric not worried about fuel infusion but would like it to stay in place without bubbling.
Best, DennisT
