I got it to work with that last method (Paste and wait to dry) 
It did take a little off, but not enough to effect anything 
One side is done, now onto the rest !
I'd say if I was to put on more layers of wax, I wouldn't have to worry so much with that first layer down ?
You could have used a polyurethane over the paint.. wouldn't touch it at all as its an oil based finish. You can mix Gloss and Satin or Matte so you don't get too much of a shiny finish. You cant now you've waxed it though unless you now take all the wax off as nothing is going to stick now
