Well, I had to give this a try! My first attempt:
I looked up the MSDS sheet for the compound in uniservers' OP, the active thing in it was hydrogen peroxide, at 12.5%. There turn out to be several brands of 40V or 40 Volume Developer, the kind I got at Sally Beauty Supply was rated at 10-15%
I left a coat on for about 13 hours, but this was overnight and in a garage, so no sunlight. Will see what the results are.
