Yes.
Optimum Poli-Seal. Polishes and seals in one step, needs no cure time, and works on paint, glass, chrome, and plastic. It's also almost WOWO.
Poorboy's Polish w/Sealant. Polishes and seals in one step. Works on paint, glass, chrome, and plastic. Needs 1 hour to cure.
Zaino Z-AIO. Polishes and seals in one step. Works on paint, glass, chrome, and plastic. Needs no cure time when topped with another Zaino product, or when applied with Z-FX. Needs 24 hour cure time if applied and buffed off with no following products, or if a following product is not Zaino.
There are others out there. I personally feel that Klasse AIO and Klasse SG are garbage products and were good in the 1800's or whenever they first came out. Newer technologies and newer products have allowed for much better options, several at lower pricing as well.
