Iv a bit of work to do on my fish and I was thinking on how to match the colour and Im after getting my hands on the colour pigments for making candles.
Iv already tried some in a small mix of epoxy(and it worked nicely) but the board is poly(and Iv been to lazy to test it yet) so has anyone tried this before?
I was thinking of mixing it in with the cabosil to fill in the ding first and then a layer of glass over it and one final layer of resin just to make sure tis sealed.
Hi High-pockets.
I’ve tried a bit of color matching with poly. None with candle colors though. It’s all been resin pigment and tint. I didn’t come out perfect but I learned a lot along the way. Here’s a couple basic guidelines I’ll pass on from my experience.
Poly is blue to start with and it goes clear after it hardens. That means your uncatalyzed color is going to be different than your hardened color. Do some small trials to see what the finished color will look like.
In small jars mix concentrations of the colors you’ll use. Then take from them to mix your batches. For each batch you test, save a small uncatalyzed sample incase you have to screw something up and have to mix another batch.
Color darkens with depth. I’d fill your repair with white-ish filler then try to make your color layer the same thickness as the original. Remember the original is probably one tinted glass layer unless it’s a full tint and in the rail lap.
Try to make your filler the same color as the surrounding foam. If your color has any transparency then difference is base color will change the final color look different. If the original foam is yellowed, matching the filler to the foam will be a challenge all it’s own.
Same goes for your color trial sample batches. Test them at the same thickness over the same color as what you’ll be doing on the board.
As a tip, you’ll probably get more hits on this thread is you change the name to Colour Matching instead of Colouring Resin. There’s a ton of info on coloring in the archives and guys get tired of answering the same questions.
Most importantly of all, respect the guys who can match color well. It’s an art. My experiences have taught me to respect them even more.
What color are you matching, grey, orange or yellow ? I have a few PU pigments if you need some. I need to get my G10 fins back from you for Fuerte this week.
