TIP: To better see the contour as you are sanding, darken up the flat base of the fin assembly with pencil.
The lower picture shows the contour after some sanding. There is more sanding needed, the penciled sides are still showing.
Here's a good fit of the wide root edge over the curvature of the BT-55.
On the forums, David Scigs has mentioned the Krylon Industrial Acryli-Quik spray paint is the old, original formula Krylon. I eventually gave in and ordered four cans from Grainger's. I had to drive across town to pick it up.
David was right - it behaves like the old Krylon. Please note - this is not the Krylon you find at WalMart or Home Depot.
The great thing - it dries fast and you don't have to worry about re-coat times!
It may not be as opaque as Rusto 2X, but I'm tired of cottage cheese rough finishes.
Note - this gloss paint still dried flat when sprayed in humid conditions. We did have cooler weather a few days ago and I got a great gloss finish.
One of the early undercoats showed some balsa grain!
More CWF was rubbed in and sanded smooth. Another coat of filler/primer, sanding and another white coat.
