I haven't had any peeling experiences with the SC 9000. I use it over Createx and Wildlife water based paints, and also over rattle can paints, like spray on Krylon Glitter.
But I've never immersed one of my lures in water for any length of time. I've fished them all day, and never had a problem.
I used to have problems when I used epoxy over wood lures. Water always seemed to find it's way in, eventually, and start the top coat and paint scheme lifting.
I never had that problem with plastic bait repaints, either.
I'm wondering if the issue is water penetration.
I have only used SC 9000 on one wooden bait, a one piece glider, made from Paulowinia (thanks Gene) that I soaked in Minwax Wood Hardener first, before I primed it. I wet sanded the primer, after each of the two coats I gave it.
So far, no problems, even after a few stripers.
But I wouldn't use wood if I were making musky lures. It's too soft, no matter what I've tried to make it harder.
I really think PVC is the key, because it's totally water proof, so the performance of the top coat isn't critical in terms of keeping water out.
I have to share a funny story.
Talk about making things more complicated than they need to be......
Last winter, when we arrived at the lake I wanted to fish, it was blown out, and the lifeguards wouldn't let us launch our boat.
So my buddy and I walked the dam, throwing swimbaits.
He was throwing one of the first surface gliders I had ever made, which was four years old. It was made out of old douglas fir, salvaged from a jobsite, and painted and sealed totally with rattle can paints, over a Minwax Polyacrylic sealer.
He hung the lure on a buoy rope on a long cast, and had to break it off. It was frustrating, seeing it floating there on the rope, and not being able to go get it.
The next week we went back to the lake, launched, and, with the lifeguard's permission, went into the buoyed area looking for the lure.
We found it, cut the trebles to get it free, and saved it.
When we checked it out later that day, the finish was perfect, even after being in the lake a week.
It's back in service.
So old, oil-based paints are really great, too.
I have been making some 4" four piece swimbaits and one piece walking baits out of PVC, and painting them totally with rattle cans.
I love that I can do the priming and painting completely in one day, and fish it the next day if I want to.
I've found that, if I let the white primer dry for two hours, I can spray on the simple, silver or white base coat, and then, within 15 minutes, spray on a shoulder and back layer, and it bonds into the base coat, and dries hard.I originally left the top coat off because I didn't want to lose the shiny silver finish from the spray on aluminum paint.
I actually did a crackle finish by mistake, when I used gloss white for the basecoat, and then sprayed a light black on the back and shoulders almost immediately. The black crackled, exposing the white, but it still dried hard. Dumb luck.
For someone like me, who likes immediate gratification, it's ideal.
And I can test new lures and basic paint schemes so much faster, and then duplicate them with a more complicated paint scheme, covered by SC 9000, for production.
