Hey foxtrapper, don't feel that way. BillNorth just feels very strongly about his method. I understand his thinking, sometimes I think my way is the best and only way, only I've not been able to convince everybody else of that.

I'm in your camp and I'll never believe that an extremely thin layer of SG needs 24 or more hours to cure before the next layer of SG can be applied with excellent results. I will also say that what one group believes to be true, the BillNorth group in this case, against what another group believes, short SG drying/curing time, makes either group wrong or right. There are plenty of people who believe that the BillNorth Way is the best way, which includes several people who have respected opinions on this subject.
I'm just not in the camp of BillNorth Way believers. I believe users of shorter, drying/curing times end up with just as effective protection for their paint. People like to point out that drying and curing are two separate processes and sometimes they are, although when paint is full cured it's also fully dried. It's just that when SG is applied as thin as it should be, which would equal about less than half the thickness of a piece of paper(how thin is that?) it doesn't take 24 hours to dry or cure. I've read that SG has to cross-link and what not with the paint. IMO, no way. By the time the OEM painted surface of your vehicle has reached your driveway it's fully dried and impervious to any kind cross-linking between the paint and a paint protectant. The best that can be hoped for is that the protectant of choice is bonding to the microscopic irregularities of the paint surface and nothing more. Cross-linking, in my way of thinking, infers that some kind of molecular, fluid exchange is going on.
Anyway the subject of SG can be best described as,
We agree to disagree, on the application and waiting time between layers. Without an electron microscope nobody knows what's going on when we apply SG. Personal opinions affect our expected outcome and bias our expected end results towards that end.
