and gel coat have been repaired on my 1994 Edey & Duff 11' Columbia dinghy
. The teak
has been cleaned, brightened, lightly sanded and oiled.
The dinghy looks new now.
The manufacturer covered the teak rub rail w/ this Taylor Made / Perimeter Industries 3/4 Round Gunnel Guard
flexible cushion. It has a white woven polyester cover over the heavy duty internal rubber. On my boat
it is retained w/ one million screw / washer fasteners. I removed the gunnel guard to permit
best access to the teak for care, also to better clean the polyester. The gunnel guard ends are covered w/ leather.
cleaned up very nicely, with the exception of some gouges and blemishes that did not sand out. There is also a crack in the pocket for the tiller. I picked up some material at West Marine
last night to fill the crack, the gouges, then match the gelcoat
The crack and gouge repair was performed using West Marine Marine Rx Epoxy Repair
putty. The West Marine Non-Waxed Laminating Gelcoat
was rolled on, followed by a finish layer of this West Marine Waxed Non-Laminating Finish Gelcoat
The entire hull
now has multiple layers of new gel coat.
The new gel coat was applied w/ a smooth roller. The result was an orange peel finish. There was also specks in the finish, from when the gel coat kicked. I lightly sanded between each layer to remove the specks, but not to remove the orange peel. Also, there were several layers of finish gel coat used and that material requires sanding
between layers. That light sanding
(between layers) was done by hand, using Festool Titan 2 6" sanding discs, wet.
There were several types of gel coat used, all was white color, tinted as shown below. The majority was the Evercoat Premium Gel-Kote
. I put on over a gallon of this material. I also used the West Marine Finish Gel Coat
. I put on two quarts of this material, sanding between layers.
The Blair Tornado II Paint Shaker
is a VERY handy product. It is great to freshen-up a can of material that has sat around for a while, or to mix-in color as-shown. This gets my strong recommendation. It mixes round or rectangular: gallons; quarts; pints or aerosols.
This Evercoat Gel Coat Document
is the best document I've found w/ information on using gel coat.
Here are my recommendations, to reinforce their information. Ensure sufficient hardener is used. It is better to use too much and be forced to discard material because it has kicked versus not having enough hardener. Ensure the color is spot on between batches. I did not have any luck spraying, so I rolled on the material. The addition of a small
amount of acetone into the gel coat, prior to adding hardener, is helpful to get a smooth finish. STOP
applying get coat when the material kicks. It is much better to discard material than to attempt to fix problems from using kicked gel coat.
The finish sanding was done using my Festool ETS 150/3 Fine Finish Sander
w/ my Festool CT22 HEPA Dust Extractor
. The abrasives used were Titan 2, from 100 grit to 3,000 grit, followed by Platin 2, from 500 grit to 4,000 grit.
The end result is an OUTSTANDING shine, w/o even used a speck of compound, polish, or wax yet.
