Waxes and sealant can all be applied by hand.A long lasting sealant needs to stay indoors and out of water for atleast 12-24 hours to properly cure. Wax on the other hand can get wet right after application. The collinite 845,476,915 are all waxes. Only thing i recommend is use very little or else when you go to remove it your arms will want to fall off. Any extra is just wasted anyways. I think we were all guilty of using to much wax because we figured the more the better but its not the case.
