Oh and by the way, I used SalonCare Professional 30 Volume Cream from Sally's Beauty Supply for the case bottom today, after using Clairol 40 Volume liquid for the horrible top yesterday. I'm pretty happy except for the front, left corner, which I need to re-do next sunny afternoon I have free.

So I had a few faint light-brownish spots remaining after last weekend's massive effort to remove the worst yellowing of any XL machine I own. Today I used 30 Vol Cream for approximately 2 hours and 15 minutes in the bright morning sun, and the top is now just about perfect. I'll apply ArmorAll to help protect the surface and call it good. :)

I don't think you'd want to do that. Peroxide isn't something you want getting on anything it shouldn't be on, so you'd have to be in a really controlled environment to start with. And then I just don't think you'd get any advantage out of it, because if you spray liquid hydrogen peroxide, it's just going to drip and dry anyway. The reason you use it as a paste is so it stays in place and takes a lot longer to dry.

 

It's not hard to use a brush to get an even coating of whatever paste/gel solution you're using. And anyway it's not so much an even coating that you need as it is just having at least some of it everywhere you need it. As a liquid, you're going to end up with totally bare spots where it's just dripped off.

which is why people that use liquid form, have the parts submerged in a clear container
