Gelcoat Repair Advice
« on: April 12, 2014, 10:41:21 PM »
Just got home with the new boat, 20 hrs of straight driving from Phoenix to Portland, one way!

and wanted to fix some gel coat issues.


Read a lot about Polyester resin and I have used Marine Tex before.

Picked this stuff up at the local store.


Says it can be coated with gel coat.

This okay or is there something better in terms of use and longevity.
When I shook the can of poly resin it seemed very fluid and I figured it would be hard to fill a vertical repair with a runny resin.
Is there something better to use?  They had two other poly resins from the same brand there but not sure which to use?

I don't know why any of the others haven't responded yet, but I'm sure they'll be by soon.  I've always just used custom tinted polyester gelcoat and Cabosil or colloidal silica as a thickener for those types of projects.  With a good color match you can do quality repairs by just wet sanding down to a very fine grit and the repair is virtually unnoticeable.  Do you have any marine/fiberglass places anywhere near you?

I took that stuff back and bought the Dame brand of poly gel coat.   Worked l like a champ,  only issue is the white is too white.   Need to tone it down some how.   Mix it with gray? Or black maybe. ?

Any input on matching the factory white?

That's why the pros make the bucks - it's an art and sometimes even they can't get a good match.
