Before and AFTER

It hasn't taken quite as long as the lack of blog posts would have you believe, but the refurbishment of Flying Scot 338 is nearly complete. In addition to the fairing and painting, I've just finished replacing the gooseneck and standing rigging, installing a boom whoopie, turtle bags and guy hooks. I hope to get the transom port, bow bag, and stem band on before the Boathouse Regatta this weekend. I am SO glad I have a Flying Scot since the class builder has been SUPER helpful including instructions with all of the replacement parts.

Painting recap:

After talking to another club member who did the same paint job (but rolled everything) I should have been more aggressive with sanding the primer. I was concerned about sanding too much off and not hiding the yellow gel coat so I wet sanded with 220. My friend said he used 80-100 on the primer which I now wish I had done (with a long board)...but time was limited. I didn't think I'd have a chance to put a 2nd primer coat on.
I am very impressed with the shine and durability of Interlux Brightsides so far. I don't think I've scratched any paint off, though it's only been a couple months of light use.
During the refurb, I decided to tackle the bottom as well, painting it with VC Performance (a 2-part epoxy) and given that experience, I think I would be more willing to attempt a 2-part poly for the topsides next time. A warning about VC Performance though: it is extremely thin (runny), being designed to spray on. They say it is possible to brush/roll it on, but it would seem far easier to spray given my limited experience. My "spray rig" consisted of a $99 compressor and $15 gravity fed gun, both from Harbor Freight.


As earlier pictures showed, my centerboard was in terrible shape. The leading edge was so badly damaged, there was actually a large accumulation of clay between the lead balast and the outer fiberglass causing a bulging in the airfoil shape. I ended up cutting out a curved section of fiberglass from the leading edge (both sides) and repairing it with about 4-5 layers of 1.5oz mat. I faired the repair and other leading edge defects with Interlux Watertite and finished with two coast of VC Performance (after removing LOTS of bottom paint) the board looks almost new.

Did you paint the VC Prerfromance over anything else, like a primer?

No, the VC was applied to sanded gelcoat and some areas of fairing (Interlux Watertite). If I had more time/money, I would like to have applied the Interlux primer to seal the gelcoat cracks, but I dry sail so it didn't seem essential.
