Any residue, whether from desiel fuel or bug guts is going to smear, whether you have something on the glass or not, so yes, there will be that reaction.
Will the wipers and washer fluid attack the AquaPel and cause it to smear?
No, as it is a hard coating, not a dressing like what you have used. Most washer fluids contain some percentage of butyl cellosolve and that will attack most any thing. Ever see some cars where the paint has bubbled around the fluid nozzle?
That is caused by the butyl content of the fluid.
It will last 3 to 4 months before reapplication is recommended.
In areas that do not receive a lot of rain, etc, since with any of these products, they still require the wipers at speeds below 10 or 15 miles an hour, the wipers are not used as often as say in Seattle. It may last up to 6 month or longer, but PPG likes to stay on the safe side and state to reapply every 3 to 4 months.
Back to the windshield wipers, and if they are not used as often, the coating is not removed, IE, the coating is not abraded away by the wipers wearing it off.
