Inspiration came from a Glow in the dark vessel bowl sink that I molded up some years ago.
Step 1: Materials List
I used "House of Color" Kosmic Long Glow Blue on this project but I suggest trying Risk Reactor as they specialize in photo luminous and UV fluorescing pigments in many different colors at a better price.
Pint of automotive acrylic urethane clear and hardener.
Red Scotch Bright pad or sheet of 400 grit wet or dry sand paper.
Masking tape and paper.
Carbon filter respirator for automotive paints.
Spray Gun and compressor or optionally use "Preval" spray kit.
Step 2: Prep Work
Be careful not to sand through original white finish. If you do sand through use a can of white "Lacquer" as a base coat to repair the solid white finish. Using cheap enamels will result in paint lifting or wrinkling with the clear coat.
I chose to mask off the top of the lid and leave that the original finish.
Step 3: Mix Clear Coat and Glow Powder
Do not rush and constantly stir or agitate your paint gun cup as the glow powder drops out of suspension fast.
Do as I say not as I do. Use rubber gloves while mixing and spraying.
I chose to spray the underside of the seat first then flipped it over onto bolts and nails I put in the bumper and hinge holes. This allows the seat to be sprayed flat , reducing the chance of runs.
Allow to dry at least 12 hrs. then reassemble seat and install. The Long Glow Blue from House of Color charges up pretty well under incandescent and fluorescent lighting. Risk Reactor has a green that has tremendous storage and intensity.
I really prefer the look of not coating the top of the lid, as after the lid is closed and lights out, as it has a nice glow about the perimeter of the lid.
Remember to make sure you leave the lid up and lights on for half an hour before bed. With my bath lighting mine charges sufficiently that I can find the target 5 hrs after bed time.
A word of advice on purchasing glow powders, The additives described are photolumenous but are not the type that glow under a black light. Risk Reactor sells both types and more. I have done commercial projects with other clear additives that fluoresce under black light illumination, some amazing effects can be achieved with these types as well.
More Instructables to come! Thank You.
