I know a lot of HPDE/Autocrossers/Club racers use this. They swear brake dust, etc .. literally washes off.

It seems a lot like the Klasse AIO/SG combo -- but this one, you only need once and you can layer it.

Any supporting vendors sell this and can comment?

TIA

it's not as good as Klasse. It's harder to apply and doesn't leave as good of results. And yes, I have first hand experience.

have it and dont use it.

I dont use it because the stuff is so fricken hard to get off!

Yes I have heard of it. I don't like "All In One" - type products. (With the exception of Klasse AIO which is alright).

Product description is sooo similar to any polymer sealant it's funny.
