Drill Holes with Krown Rust Protection?

What about the rust warranty? Isn't it like 5yr 100k? I always wondered about this. Why isn't the manufacture covering this?

For corrosion warranty coverage, there has to be a hole in the body or frame. For the new aluminum trucks only, ford now covers the paint if it bubbles or comes off while the corrosion warranty is in effect.

I wouldn't use crown again
I just traded in my 2008 f150 for a 2016 ( slightly pissed off about spending $47,000 for a new truck with factory dents in it) Well let me tell you about my experience with Crown on my 2008. Before spraying any vehicle they are suppose to silicone any and all weatherstripping or rubber before. The crown oil has some form of chemical reaction with the weatherstripping and rubber and causes it lose its form over time and almost turn into mush. First time I noticed it I went to the dealer who right away knew it was from the rustproofing and would not replace the weatherstripping under warranty. So crown stepped up and replaced the long strip of weather stripping at the bottom of both doors on both sides. Three years later the weatherstripping faltered again and I fought with crown again to replace them. Just before I traded in my truck I noticed that all the windshield sprayer hosing under the hood was starting to falter just like the weather stripping. Just remember no matter how much you rust proof your truck it will not stop the rust from forming especially from the chamfering of the box liner bed or rail caps. I have therefore decided not to rust proof my 2016 f150 with the mandatory option of factory body dents.

Different states and different municipalities use substantially different chemicals to melt ice on the roads, and some of these chemicals are EXTREMELY corrosive to metals, both steel and aluminum.

These are from my 2011 so they may not apply. The first is a factory hole looking from under the truck cab looking out. There are several of these along the length of the cab. They are taped from the factory. Several had the tape peeling off and several had no tape but residue around where the tape was. The metal is painted and there are drain holes but if those get plugged, junk will be trapped. I applied Fluid Film inside and taped them back up.
The second and third are of the void behind the front tire. It appears to be sealed. The crud I got out was wet. I sealed off the hole above in the engine compartment so hopefully no more stuff will fall in there.

If someone is worried about rust, then buys an aluminum truck and wastes money getting a rust treatment, maybe they should have just bought a GM or Ram product. Body shops I've asked about it asked if I was nuts (Right now I'm in the rust belt on family business and the shops I've asked both do corrosion protection and rust repairs).
As for old steel bodies, my '07 lived in northern MN where it seemed they dumped 1 ton of salt per block. And even without rust protection, there was virtually no rust on that truck. Only protection--self service car was every other week.
If the OP has corrosion issues in the future, it will be interesting if Ford void his anti-corrosion warranty due to the "anti rust" treatment.

Wow. I can't believe how ignorant people are when it comes to aluminum. These people that think they are smart in their comments criticising the OP. You have no freggin idea!

Aluminum may not rust but it sure corrodes in the presence of salt and with many parts of the truck still made out of steel I don't see how undercoating would be a bad thing. Steel and aluminum also react with each other causing corrosion and if any isolators between the two metals were missed or poorly designed you will have problems in the presence of moisture or salt.

About to get a 2015/2016 F150 Krown rust protection applied and just wondering if people are generally having them drill to spray inside the body panels or going without drilling? My initial thought is there are still metal components inside the body panels that wouldn't hurt to get sprayed at the same time...
