Last fall I attempted, somewhat unsuccessfully, a few minor gel-coat repairs on my 1976 13-Sport with Spectrum Color gel-coat patch paste. The problem I experienced was improper color match. Assuming the entire hull color of my Whaler was Desert Tan, I first used the Desert Tan patch paste, but it was too dark; then, assuming my hull is not Desert Tan, I used the Light Grey patch paste, but it was too light. Finally, I mixed both paste colors to find the closest medium. But still, the match is not perfect.

What, exactly, is the true color of my 1976 13-Sport’s hull? And, has anyone else experienced a bad color match with Spectrum Color gel-coat patch paste?

Your 1976 Sport 13 is Desert Tan on the inside only. The exterior is Outrage Grey. For more on what colors were used on what models, see:

I suspect the original colors of your gel coat have changed over the years. It is very difficult to get an exact match without adjusting the gel coat once you get it and test it on your hull.

You may even find that different places on your hull differ in color from variations in the exposure to sunlight.

is this where i can get some outrage grey gel coat patch?
