100% Rejex!!!! Some people aren't too crazy about it - but when quizzed, they all seemed to apply one coat and/or took the sled out for a drive before the 12 hour cure time. I research the crap out of stuff to a ridiculous point, and I admit that is one of the biggest secret to getting this product to perform perfectly.
My routine is to apply 2 to 4 coats with 12 hour cure time between each coat. (And don't drive the sled before it's cured 12 hours either). It goes on really thin, and with each coat it gets easier and easier to apply and take off. And you'll have one of the most resistant barriers against carbon and metallic dust you can find.
There are sometimes we can use an air gun to blow the dust off. As stated in an earlier post on this topic ... if you do use an air gun ... don't breathe in the dust!!! :nono
Hope this helps.
