Hi guys. I recently used GG glass sealant and Adams Ceramic Boost over it. I understand that's not recommended just thought I'd do it and see what happens. I think it boosted the glass sealant w/o the extra money to buy Glass boost (already had ceramic boost: great stand alone spray sealant) Anyway, opt has an excellent glass clnr with protection... maybe Adams will release one some day. Buying all these cleaners, boosters, sealants etc is very costly..."think outside the box".
