Well …I did it again. I get so excited about painting a board I forget to tape off the stringer! Half way through I’ll notice and go $h!t…I did it again :(. Any body else ever do this?? The problem is it wants to crystalize over the paint on the stringer when you glass it…sometimes. Oh well …better luck remembering next time!

Yah, I’ve done it. The first board I painted I did not know you were supposed to tape off the stringer. It came out fine, though. You might be able to clean it up with your small block plane. Mike
Howzit Krokus, I just glassed a board that the shaper painted with out taping the stringer off, no crystallation. I think what causes the problem is the water in the paint doesn’t dry as fast as it does on the foam or gets trapped in the wood, I’d let it dry real good or even hit it with a hair dryer or heat gun to dry out the paint on the stringer, might do the trick.

Krokus- Another trick that will work: brush a coat of lam resin over the stringer and let it dry before you laminate it. This will seal it and prevent it from crystallizing. Also works with blue and red paints. -Carl
I’m letting it dry for a coupla’ days before I glass it. I have another one to paint and then I’ll glass both at the same time. I think it very well could be water trapped in the wood. I’ll hit the stringer with some UV lam resin before I glass it. Have had way better lams since I started letting the paint dry overnight. Running my new A/C unit is keeping the humidity down in the shed…helps a lot.
Thanks,
Krokus
Okay so you’ll let it dry a day or few first - let us know how that works, what color and brand of paint.
My two cents worth would be that you can always put a pinstripe over it if there’s a “crystallization” problem.
Ted Wilson at Fiberglass Hawaii warned me about this and sure enough, the fluorescent red he sold did show a major crystal problem, but that wasn’t all, the painted blank, left in the sun, turned brown in a couple hours; then back to red when I glassed it. The sprayed board looked densely colored and even, the glassed board was streaky and thinly painted, despite a lot of paint I knew was on it. Pigment for me, for all solid color boards. It’s quicker and more dependable. Tints I will still consider for spray, and I’ll gladly fine sand the blank to take them evenly.
Howzit Honolulu, The fluorescent paints that F.H sells and probably all fluorescant paint wil fade faster than anything. I’ve seen ot happen many times since the paint isn’t colorfast. I always mix it with a non fluorescent color fast paint to prevent fading. I use fluorescent paint to give some vibrance to my paint jobs and that’s about all they are good for. I was talking to Dutch at F.H. and they are going to start bringing in Nova paints which are lot better than what they are selling these days. I just glassed a board with paint on the stringer( some black, red, etc) and got no crystallation. What is strange is that fluorescent paint doesn’t usually crystallize, so I’m guessing that the paint was to heavy or not totally dry. Aloha, Kokua
