I want to use a sealant on my truck this weekend after I wax it. Out of the Meguiars NTX products which would I use? The paste or tech wax? Both say they protect and seal? The auto parts store around here mainly carry Meguiars products and turtle wax products so I am limited to what I can buy. I will be waxing with a Meguiars wax just want to know if I can use the tech wax or paste on top of that?
