Someone sent me some of this and i will be trying it on my motorcycle this weekend. It's got a fesh coat of NXT right now and topped of with liquid performance detailer which is a heavy waxy one different than other detailers. also a few coats of #16 under it all. Can i just apply the opti seal or do i have to somehow remove all the previous stuff? Also, how do you apply this stiff? he sent me a small vial, but i have no instructions.
