Vans Aircraft RV-12 Airplane Build, Section 34: Canopy Installation (part 14)

Reference: Page 34-16; 7.0 hours

This entry is about final prep of the RV-12 airplane canopy aka sanding and filling fiberglass! In addition to fill I put a thin layer of epoxy over the exposed front edge of the canopy bubble. (Sorry no picture.) The reason for this is I want to paint the underside of the canopy fiberglass and don't want the paint to craze the plastic. Below are pictures of the final outline of the canopy fairing "wings".

I used UV Smoothprime to fill the pin holes in the fiberglass. First coat is applied using a scraper (old credit card, straight edge razor blade) to scrape the product into the holes and release the air in them.

After this has dried additional coats were rolled on using a small foam roller for a total of 5 or 6 coats. Also a foam brush was used on the spots a roller wouldn't fit.

Here's a look at the sealed canopy edge.

That's it for this entry other than a whole lot of block sanding!
