What is the best way to measure coloring for gelcoat
? I'm working with polyester gelcoat
I experimented and found that about 4 drops of yellow for each fl oz of white gelcoat is a match for the interior
However, my drops were crude because the cheap
pipette I used to measure the drops were not very good and the size of drops varied a great deal.
I'd like to get this ratio as accurate as possible so I can produce consistent color from batch to batch.
What is the best way to measure out the amount of color? If it's by weight, does anyone have a recommendation for a scale and should it measure to the 0.01 gram or is 0.1 gram accuracy good adequate?
Not sure how much gelcoat I'll be mixing at once, but likely in the 2 to 6 fl.oz. range.
