Hello,
I finally pulled the fish from the basement, where it
sat for the last 5 years. While washing it, I decided
to sand off the paint that had been put on by the
previous owner. What I found underneath can be seen
in the pictures.

The first picture shows where there is about a 1 inch
square patch of exposed mat near the bow. The second
shows circular spider cracks found on the hull
underneath the cockpit.

I plan on grinding away these areas, re-laminating if
necessary and then filling over with some and fairing
compound. Am I opening up a can of worms? Is this
going to be more work than its worth? After I finish
should I paint the hull? What type of paint should I
use?
Thanks in advance,
Greg

Hi Greg,

Sorry about that. I posted all of the photos I had on
the group under the folder hull damage.
Thanks,
Greg

I gather that you attached some photos to your

Hi Greg,

By the way, welcome to the group.


I took a look at your photos......

Here's my 2 worth:

The chipped section -
Using a putty knife, awl, utility knife - something like that remove all the
loosened gelcoat and then sand or dremel the edges back a bit more so you
are into an area where there is a good solid gelcoat to glass bond. I don't
recommend grinding/dremeling/sanding into the glass fiber unless you truly
need to make a repair there. If the glass roving is delaminating rather than
just scuffed you may want to add some resin/milled fiber mix to stabilize
it. If it is really bad you will need to cut it out and patch the glass
before continuing.

Tape off the area and fill the depression with gelcoat. You might add a
small amount of milled glass to the gelcoat for a bit more strength. Sand
smooth to match the surrounding hull. Keep in mind that gelcoat takes a lot
longer to "kick" and then totally harden than plain polyester resin does. I
usually give it 12 to 24 hours before I sand, depending on ambient
temperature and humidity.


Hairline cracks -
Use gelcoat putty to fill the cracks. Sand smooth.



Finishing the job -
Repaint the bottom.... you could use two part epoxy filler primer and forego
the gelcoat paste. There are several ways to repaint - Two part epoxy paint,
re-gelcoat, one part paints, such as EZ-Poxy. You will have to do the
homework and choose what you like to work with.


A note on epoxy paint (and repair materials) - If you do a repair using
polyester resin and glass (Fiberglass) in an area where epoxy has been
previously applied the epoxy material must be completely removed and cleaned
before applying the fiberglass materials. I mention all this stuff about
epoxy because it is all the rage right now. It has its place for sure, but
IMHO it's more expensive and a bit more difficult to work with - and on a
Sunfish the benefits are minimal.
