I've been working on my cowl, a new pepto cowl. I admit that do to extra blisters for the H2AD my top cowl, I had all sorts of fab the required filling. It was a grand experiment . . .
The lower cowling I went with the West System fill process, resin and micro. The issue is that after 6 coats and wet sanding, I still had visible 'divots' around the supporting hex core, mostly in 'horizontal' surfaces, nothing I would expect a high build primer to fill. Pinholes? Nope, not a one.
I'm going to go with a swipe of polyfiber epoxy filler , wet sand smooth, and a thinned coat of west resin over the top of that, wet sanded, then shoot a high build for wet sanding/guide.
Is this dumb?
