I have had Zing graphics on my RM 400 for over six years now with out them lifting, and I have had the perforated graphics on my YZ 465 for around three years now.
With the RM, I flushed the tank with prepsol (wax and grease remover) and then washed it out with soapy water four or five times and then left it sit full to the brim with soapy water sealed air tight for three days to remove any vapors that may still be in the plastic. Then I cleaned the area for the graphics with wax and grease remover or nail polish remover and applied the graphics to the tank with the soapy water still inside the tank. Then I let it sit and cure for a few days before emptying the water out.
The YZ was a bit different, I sanded the tank back for weeks so most of the vapors would have escaped in that process so it was just a quick wipe with wax and grease remover over the freshly sanded smooth tank and on they went.
Something I have always done with them is to drain all the fuel out of the tanks and leave the caps off after every use.
