Oh man, I'm having a really difficult time getting the splotching off the 5.25" bezel. You definitely do not want to let the solution dry out. In trying to get the splotching out, I'm reapplying the Salon Care 40 every 45 minutes and putting it back under the light. The splotching goes away, but when I wash the solution off, the splotching returns, but not as strong as when there is dried out solution on the bezel. So I can put the solution back onto the bezel, put it in the light for 30 minutes, and the splotching goes away. I can take the bezel out of the light and let it sit on the table with the solution still on it, and the splotching does not return. The splotching returns when I wash off the solution. It is very curious. Maybe I can let the solution air dry onto the bezel?
Only the 5.25" bezel showed the highly sensitive behaviour to drying. But after so many rounds of trying to remove the splotching, I think the bezel is too white to go into a system. How long does it take to get some yellow back? If I put the bezel back under the light without the solution, how long to get 20% of the yellowing back?
EDIT: I was wondering why the circles of splotchiness appear. Are they areas whereby there was air bubble forming a lens to focus the light down onto a spot on the bezel? Are the splotches areas of non-dried solution? And is there a limit for how bright bezels will get? Can they get much brighter than their original colour? What were to happen if you cut a slice of plastic off, say about 1 mm down. Will this plastic be yellowed, the original colour, or the retrobrited colour?
