The last video of this series! Here I cover a great product from Pettit Paint! Their barrier coat system called Pettit Protect.
An easy to use protective system that helps prevent the formation of blisters in the fiberglass. You can find more information on this product HERE…
This system is mixed 3:1 (3 parts base to 1 part catalyst) and if needed can be thinned up to 10% overall volume with Pettit 97 Epoxy Thinner to help with rolling the material out a bit smoother.
Recoat times range from 3 hours (minimum) to 14 days without having to sand the surface. If you happen to go beyond that time window, sand the surface with 80 grit sandpaper, wipe the surface clean and continue with the application of the next barrier coat.

Hi,
I have a quick question my six years old son has 82 17′ Proline.CC overall condition is pretty good I have a few small cracks in Gel coat and screw holes to repair then we would like to change the factory color was off-white or almond and we would like to make it bright white. And my question what would you recommend gelcoat,Epoxy or paint and I’m not looking to do a quick and dirty don’t mind the labor would just like the best. Something that we might get A Nother 20 to 30 years.
Thanks,
Greg Joliet

Hi Andy-
First of all, what a great and informative series! You have inspired me to tackle the rudder on my (new to me) Hunter 30. When I purchased the boat this summer it was on the hard and I noticed damage and delamination on the bottom leading edge, with copious brown staining.. I figured at a minimum it would have to be rebuilt. Holes drilled over the entire top side (rudder laying on table) produced wet, brown foam and applying pressurized air to the holes caused foamy water to seep out everywhere, including along the seam around the perimeter. Clearly, it had become saturated. After cutting the glass, leaving a couple inches around the perimeter, I quickly found that the glass, at least on the main body of the rudder was still bonded to the interior foam… quite well, in fact. In addition, the framework off the rudder post consists of steel (not stainless) welded to the SS rudder post.. and appears to have considerable life left, albeit covered in surface rust.
My original plan was to remove the frame and post, have the steel plates remade, and rebuild from there. However, the foam body is still extremely hard (requiring a hammer and chisel to even chip), and securely bonded to the glass. I’m considering leaving the rudder opened and allowing it to dry, then cleaning the foam and steel, coating with an epoxy and then refilling the void I’ve already dug out with 16lb foam.
My worry is that this would possibly create internal weakness down the road. Do you suppose an epoxy would bond well to the existing foam, so long as it is dry?
Although I’m quite the novice, I’d have to say that this rudder is built like a tank and would have probably made it another decade in fresh water without failure, but I wasn’t going to know that until I took a look..
Thanks again for your good work!

Thanks Andy, for your very entertaining videos. They bring me back to my youth when I did a bit of fiberglassing on many small boats but I tended to get more resin on myself than on the projects! I now have a 45 Gulfstar that needs some topside crazing and portlights repair and you have given me not only encouragement but knowledge as well.
Thanks and keep up your sense of humor.

Thank you Paul! Good luck with your projects!
Great series, curious what material is best for a spline?
Where can spline material be purchased?
Hi Todd, what do you mean by spline? Sorry, my mind is not working today :-/
On this project. are you done with just the barrier coat or do you need to finish it off with a top coat? I’m redoing a small centerboard keel which delaminated and thought I’d follow along on this project roughly for the fairing and painting.
