Because I have too much time on my hands, I bought four brands of white UV paint for comparison:
-- UVfx from Amazon at $1.41 an oz. (8.45 oz. bottle)
-- GloMania from Amazon at $7 an oz. (2 oz. jar)
-- Rosco from B&H Photo at $1.31 an oz. (32 oz. can)
-- Wildfire Optical White from Wildfire Lighting at $2.31 oz. (32 oz. jar)
I painted a rough piece of plywood half black and half white with standard paint. Then I painted stripes across the board using the UV paints. Because of the roughness of the board, I used two brushed coats of the UV paint. I also made stripes using a half-and-half mixture of the Wildfire paint with water, and same with the Rosco.
The UVfx and GloMania paints were the thinnest. The Rosco was almost like regular white paint, and Wildfire was in between. Again, two coats were used for each stripe.
You can see the results for yourself. The photographed colors are fairly true to what I saw with my eyes. UVfx, GloMania and Rosco all had a distinct blueish tint. The Wildfire...not sure how to describe the color...maybe a touch of green? The next photo shows the sample palette along with part of a fake shutter I made using Wildfire paint. I've used Wildfire optical white for several years and am very happy with it, but it's the most expensive of the samples.
I used blacklight tubes in a workshop fixture to light the samples. The tubes don't cast any of the purplish background light associated with (cheaper) blacklights having the wrong wavelength. (Yes, the tubes themselves are purplish.)
So, in conclusion, your choice might depend on how much you want the paint to stand out in daylight, how much you want to spend, and whether you prefer a more-or-less blueish tint to the "white" when illuminated with blacklight.
