Anyone have experience with Loehle Wonder-Fil for pinholes? http://www.loehle.com/
szicree said:All true, but my point was that for smoothing out pocks and pinholes in a cowl, body fillers seem like just the ticket. Way easier to sand than epoxy, cheaper, dries quicker. The issue of using on uncured epoxy seems moot since the cowl was built a long time ago, and shrinking is not a problem with modern high quality fillers if used correctly. By correctly, I mean as fillers, not to fill giant divots or to sculpt a set of tailfins to make the RV look like a '59 Caddie. As far as adhesion goes, good filler sticks just fine if the surface is reasonably rough and clean. I wasn't trying to say that polyester is some kind of wonder filler, but it's not nearly as crappy as folks are saying. If used correctly it will stay put and the paint won't peel off. We're all driving around with the stuff and our cars are fine. If the paint blisters in the sun or a big slab of bondo falls off your plane, it's cuz you screwed up and not the filler's fault

Have you painted your plane yet? If so, how long has it been and how well does paint stick to the Wonder-Fil?
If you want to try another filler, then my suggestion is Rage Xtreme by evercoat. Or, lots of coats of K38 PPG primer
