HI,

I have been attempting to repair a few gel coat chips in my Supersport. First I tried the all in one Evercoat Gelcoat paste. It was easy to use, but never would harden (And I tried some of the tricks mentiond here). Then I tried the evercoat gelcoat that you must mix. This worked better but it still doesn't get rock hard like the surrounding gelcoat. Maybe its just this brand because someone wrote to me and said they had about the same luck with Evercoat. Well west marine assures me that Marine tex will harden but before I even open the package I wanted to see if anyone here had ever used it and could comment on this ?

Thanks, Fletch

Marine Tex will repair an engine block to about 600 degrees. Will harden better than any other product Ive ever used, can be redrilled, hammered, etc. You do want to apply it as closely to the contour of the repair as possible because it is very hard to sand down.

I use Marine Tex white to repair stripped out screw holes, both with and without wood backing underneath, and sand and buff it up flush with the gelcoat surface. It's great stuff and highly recommended. BUT ONLY WHEN THE WORK WILL BE COVERED BY THE FITTING.
(I'm assuming your Whaler is desert tan).

Otherwise, for just gelcoat repairs, use the BW gelcoat in paste form from Spectrum. Most BW dealers, or West Marine, have it.

I use Marine tex on almost all of my small gel coat repairs.It is tintable, make sure you tint before adding hardener as it,s work life is short.As with most epoxies it will take forever to harden below 60 degrees.Use a heat lamp or lightbulb near the repair area in colder weather.After fairing the repaired spot, top off with a coat of Krylon #1504 Ivory gloss for a near perfect repair.At least that is the color of my 1973 outrage.It is an epoxy so it does require a topcoat.Although I do have a few spots that I have not gotten around to painting with no apparent UV damage to date.
In my opinion no whaler owner should be without marine tex in their repair kit.

I have found that if you wet sand marinetex it sands as easily as wood.

If you wet your finger you can smooth the marine-tex while it is still soft. The more you contour it to the shape you want, the less sanding you have to do later. Great stuff, still holding to the aluminum on the front of the crankcase on my 9.5hp Evinrude. (engine threw a rod in '86) I use it to fill dings in my gelcoat. Only problem is that it yellows over time in the florida sun. (helps it adapt to the tan interior on the whaler).

Ok thanks guys I will give it a try. I am not sure of the offical color of my boat, but evercoat white matched pretty well. I have marine tex white so I am hopeing it will do the same. Instructions said I could use evercoat color mix if needed. LHG, are you sure its west marine that has the Spectrum as I did not see it on their web site.

Anyway thanks for all the comments,
Fletch

I cannot resist adding this one; I once read of a yachtsman on an ocean crossing that used Marine-Tex to replace a filling that came out......

Believe it or not !

In case it was not obvious... a filling from one of his teeth...

I used it to rebuild up my keel.I'm not sure how it reacts to the interior foam though?Any chemists out there.

Epoxies in general do not affect the foam because they don't have styrene. I believe that Jim Watson of WEST SYSTEMS mentions this in the Whaler Radio segment he did. Listen to the interview.

That answer is right at the end of PART-1 of the interview; styrenes are the culprit in dissolving foam.

But listen to that interview, it has a wealth of information.
