Turtle Wax Black Edition! lol if you have a black car.

 

nxt 2.0 is great stuff. also cheap and readily available at any local store

 

I use it from time to time, and maintain that it's pretty much the best OTC wax you can buy.

 

It's a good wax for sure but you are right you need to keep it up as it doesn't have the staying power...

But for about 30bux you can get Autoglym HD at your local Wally world which is an AWESOME wax that use to cost over 70 online... Great for darker colored cars and works well on the light ones.
