i just had my car painted, then wet sanded and buffed by a detailer. they also applied a sealant. apon asking them about the sealant they gave me some as well, this is it here as far as i can tell. they seemed to have never heard of klasse at the place. i just ordered some klasse products. they told me i don't need to put anything over this sealant - and to apply another coating of sealant before winter. it seems that this sealant doesn't have much of a shine to it.. can i put the klasse sealant over it? i purchased the all in one as well as the high gloss sealant.

they told me i could put their sealant on the windows as well as wheels. yes true? anyone know anything about the sealant they gave me?
