A fiberglass canoe washed up on a friend's property a couple years ago. He
stuck it over on the side and forgot about it. I would like to fix it up
for my sons to use.
It has two holes in it that were very crudely patched with some sort of
caulk. It was also painted; much of which is flaking off.
I would like to put a layer of fiberglass over the holes, and then a layer
of fiberglass over the whole bottom to stiffen it and reinforce the hole
That will require removing all the paint. The original fiberglass is pretty
thin, so I am reluctant to sand the paint off, but I am afraid that chemical
stripper will not be kind to the fiberglass.
My older son doesn't have much to do this summer and is willing to do this
project, so labor is not an issue.
For fiberglass to stick correctly you will need to remove any layers
down to the original fiberglass so the new can overlap the old area by
at least 3-4 inches. Make sure you use a fiberglass mat cloth made for
marine use so it won't tear as strongness is the key. Several layers
are in order. The final layer can be sanded smooth to blend with the
original layer. If you don't care about the finish you can try to match
the paint using a non-water based paint. If you prefer the original
quality, then you will need to learn how to do gel coating. They sell
small kits on EBay for that. You can also get your marine fiberglass
there also. You can also tint fiberglass resin with color.
Given all the work involved, the materials, skills needed for it to
come out right, the fact that sanding fiberglass isn't the most
pleasant or safest job without good breathing eqpt, etc, I'd think long
and hard before deciding to do this.
If it was just a couple of small repairs, it would be one thing, but to
patch and then resurface the whole bottom is a big project. I'd see
what used canoes go for first.
