Thanks, Richard. It’s been 18 slow months. Must. Run. Trains.[:P]
0.015in clear styrene (back support). If I did it again, I would use 0.020in. Needs to be a little stiffer for that long a drop (9.5in). There are 4 strips.
Magic Water (base coat, waves) - partially cured for about 12 hrs. (tacky)
Liquitex gel, medium and thick (edges, runs, ripples, etc.). There’s some cured strips and beads of Liquitex Gel stuck on with the partially cured Magic Water. I used a syringe packed with the medium gel to lay out the beads and strips on a non-stick pan.
Some cotton (foam). Rolled, and packed on.
Red Devil clear caulk - goes on clear, dries clear - mixed with partially cured Magic Water. (edges, pool splash/foam). The Red Devil by itself was just to tacky/thick for me to spread. The mix is hard enough.
White acrylic craft/art paint mixed with Liquitex iridescent craft/art paint (white highlights).
When everything was cured/dried, I applied 3 liberal coats of Krylon Crystal Clear. The first 2 coats were air brushed on the falls, cause of the cotton. I think one sprayed thick coat would set the cotton good enough. The other coats could be carefully brushed. IMO. The Magic Water, Liquitex, Krylon and Red Devil all officially claim to be non-yellowing.
I don’t think it’s going to settle or yellow/discolor in my remaining life time. Should be easy enough to keep clean. All my painted rock is also clear coated - Krylon Matte Finish. I can gently wash the rock and water, if I have to. That Krylon stuff is durable, in my experience.
Thanks for taking interest.
