Well, I guess this is my first post also

.
I've used the Glare! products since last year, I think the result have been quite good.
They were sold with a good discount in Sweden, and not to pricey...at least as they used to be in the past.
I've used Glare! KnockOut, Spider, Mcro Finish and Professional Polish...and I think it protected my car quite good during the winter time (when we use harsh washing products frequently).
I've used a lot Meguiars products in the past, as well as a bunch of others like Ultima Paint Guard+, Sonax Professional, Lahega etc.
I wouldn't say that Glare! is the best or my final product, and it wouldn't hold 60 months in Sweden...but at least 6-12 months without any problem.
I guess it all depends on the cost.
I agree with Porta that it seems to be sort of the same as Fireglaze, according to them who have tested them both.
