Like many who read this forum, I 'm newbee to using the Klasse products. I used them on my 2001 Toyota Tacoma, 1 -AIO and 3 -SG followed by a coat of Collinite Insulator wax - the end result looks great! Also did the same on a new Honda Accord.
I got caught up in the debate over how long to wait before adding the additional coats of SG. So I called the Klasse distributor in San Francisco. I spoke with Bob and unfortuantely didn't catch his last name. He was extremely helpful and friendly.

I would strongly recommend that one of the senior members of the forum give him a call and get more details on the product.
In response to my question on how long to wait between AIO and SG - no waiting -"immediately"
In response to my question on how long to wait between coats of SG - no waiting -"immediately" .
When I asked him about curing time, he indicated that unlike wax, the Klasse products 'breathes' and hence can be layered without waiting. This is alo aided by the fact that they have very little solvents that have to evaporate. He did say that the final step of adding a wax layer was not needed and that it sealed off the 'breathable' layers of Klasse(with no harm done).
Don't know if this will help or confuse, but I did want to share.
Next time I do a car or truck, I'll skip the final wax and layer and many coats of SG as possible with a very short wait (give my arm a rest) between coats.
