Hello John and Kayak forum;
After searching the internet and finding and reading thru several topics, I’ve just become a member today. Please excuse my novice approach in starting a new Topic to reach out with my questions.
I’m writing in hopes to gain some of your (and or groups) expertise, opinions, concerns on re-coating a kayak I purchased 2-3 years ago.
It is a Marshall Rosa surf-ski ‘RoseSki’ used for open ocean kayaking.
It is 19’-4” in length, 18.5”, weight is 25-lbs.
The builder raced and won the Molokai-Oahu 7 man canoe race in 1980. Shortly after he stated to design, build, and sell his single man ocean ski to use for training during the off-season.
By the serial number I found on this particular ski during sanding, it looks to be from 1989 (near the end of his ski producing years).
It sat for a few years during my possession as it needed ding damage and two areas where the seam had separated between the upper and lower halves. I’ve finally pulled it down from the rafters and am about 90% done with repairing the damage so I’m starting to research what to re-coat it with. A recent quote from a canoe shop of $1000. to spray it has pointed me in the direction of having to do it myself. I have the necessary gear to do it from past car projects but never have done fiberglass.
Besides the areas that took physical hits, there is quite a bit of hair-line cracks in the Gel-Coat.
As the shell is rather thin to keep weight down (I can press areas that deflect easily) I’m speculating the hair-line cracks are from flexing and age(?). Though I’ve sanding a lot of them out.
Goal is to spray a white gloss finish and possible keep as much of the original Gel-coat underneath for what added protection it can give. Along with some of the comments on paints noted in the forum (and one I found in the internet called Wearlon Speedcoat-49), the other goal is surface durability but also a covering that can withstand the potential flexing in the ocean and during car transport to and from the ocean.
This is from the Wearlon site but it doesn’t mention flexibility - “Lastly, SC-49 is permanent and durable. But if somehow there is damage, touching up is a cinch. It has great adhesion to aluminum, fiberglass, gel coat, and to itself, and will last for many season”.
Attached are 6 photos of the RoseSki prior to my repair work last week. One of the photos shows a digital chronometer wristwatch (minus the straps) glued to the deck which indicates maybe at one time it was used for the channel race. When I got it pried off the Gel-coat underneath was still shiny.
Any thoughts or suggestions would be greatly appreciated.
