Upcoming Krown Rustproofing Experience

They drill holes so they can get the spray wand inside the doors and any other cavities that will collect moisture ,road salt and dirt. You're right, aluminum won't rust, but it will corrode and turn into a white powder under the same conditions that rust steel. if you don't like the thought of someone drilling a half a dozen 5/16" holes in unnoticeable parts of the vehicle, tell them not to do it.
What you said about the oxidation... do you think krown would prevent that from happening? I asked when they applied it and they said the majority of the research is on steel and rust (not aluminum and oxidization) so they are not sure until a few years passes and they get feedback on the f150. If nothing else it was his honest answer.
But I like your reasoning ... and honestly it can't hurt so next time I will probably let them do it.

I have always let them drill holes in previous cars/trucks, I really have no problem with it but in this case I thought it would be useless.

I haven't got mine done yet but a friend of mine did and the local Krown dealer told him there was enough factory holes or access points that they didn't have to drill and also didn't want to in case they introduced iron filings to the aluminum promoting corrosion between the two metals. I can't see it hurting anything especially when the frame, bumpers, brake lines and so on are still made of steel.

I wouldn't be too worried about getting iron filings from the drill bit, aluminum is way softer than the drill bit. But you are right about the aluminum/steel corrosion issue. The trucks are built with some sort of washer isolating any steel/aluminum contact. Something to keep in mind if you ever install mudflaps.

Im in Alberta right now but I have to drive a good 2 1/2 hours to get to the Krown place. I have my car done every year and I want the frame of my 2016 F-150 sprayed. I don't think I'd ask to drill.
