Hello there,

I have an 83 montauk that needs some gelcoat attention. I purchased some desert tan and some light grey from spectrum. The desert tan dried quite a bit darker than the existing gelcoat, and the lt grey turned out much whiter than the exising color. Did I possibly mix the gelcoat wrong? I'm really not sure where I went wrong. Does anybody have any ideas? thanks brett

You might try compounding the original gelcoat next to the repair to see if oxidation and sunlight have lightened the original desert tan color. You may find that if you remove the oxidation, the underlying gelcoat is the same color as what you got from Spectrum. Good luck!

Mixing the gel coat wrong won't alter the color of it significantly, so I suspect that is not the problem. David offers good advice. The color your boat was when new is probably not the same as it is now.

The fact is that matching color is very difficult. No two boats are going to be exactly the same. I have done repairs on mine where two different shades were required to repair damage on different parts of the same hull.

The best thing to do would be to try adding a tiny bit of black or white to alter the shade of the gel coat you have.

some people have used a bleach and water solution AFTER the gel coat has cured adn a bristle brush to blend the new gel coat with the old. The original has faded over the years. Thje new will too.. eventually. i gel coated my anti-skid on a '88 newport with Spectrum desert tan this spring. It has not faded but the deck sure looks great.
