Bud has been on lots of web boards and has been removed from many of them. I think there may even be some threads here from him (usually goes by buda, I think).
As to the products, I've used only the paint sealant. (A few years ago, now, though, so it may be different) Easy application/removal, good looks, decent longevity and it wasn't too expensive. I think "cost effective" is one of the things he pushes the most in his business.
If I were looking for product for a business, I wouldn't be averse to trying this brand based on the results from the sealant.
