what i did was used a good cleaner/polish(Megs #9)then DG 601
bonding agent then apply the DG 105 over the 601,remove both the 601 and 105 together then wait for a hour or so then top off with a pure wax i use collinite either 476 or 845.
you'll have a killer shine and LONG lasting protection,i used
a cheap orbital buffer to apply and remove the products
listed above..
Assuming the finish has been washed, clayed, and polished first:
#601 followed by #105 followed by DG Aqua Wax (actually a spray sealant). As daman mentioned the #105 is applied directly atop the 601 once it has dried and they are both removed at the same time.
