Did some fussy prep over the last few days sanding back the canard top patching, adding a little more fill and sanding again. Applied two lines of masking tape to the bottom leading and trailing edge.
Applied 4 coats of epoxy wipe, about 1.5 hours apart. Following some hints from somebody I had forgotten I tipped off each coat of epoxy with a 1.5" square bit of foam, (they used a 1.5" foam brush, which I thought a bit flash, and I didn't have any). This made everything look so smooth and nice that I left off the 5th coat, and really debated with myself about the 4th.
