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...

Absolutely not.

Why would you do that? It's an aluminum body. Anything you spray inside the panels may actually react with the aluminum or void your warranty? What is your reasoning?

I think this qualifies for the worst idea of the year award!

Why would you rust proof aluminum.....Lol

I'd just have the frame and undercarriage done.
I know the f150 does have some steel reinforcement in the doors and possibly other areas. The areas than would usually rust are the bottoms of the doors, fenders and lower body in general. Those areas are probably 100% aluminum and not worth treating.

Aluminum may not rust but its does corrode so its not foolish to ask about treating inside the doors/fenders.
I just have no idea if treating them is a good idea or not, Ford may use a coating or process that could be damaged by the Krown rust proofer.
No such thing as a foolish question...... But foolish answers are always abundant

I had mine sprayed and drilled a year ago. The truck hasn't fallen apart yet. However, after a year of Nova Scotia salty crappy weather, the truck still looks like the day it was built. I have to ask what we think the adverse affect of having the truck drilled could possibly be?

I don't know what drilling may do. Not dissing on anyone who did this. But I guess I would be worried about the unknowns of doing this with the aluminum. I know aluminum corrodes but IMHO good washing during the winter season and maybe crawling under it every couple years to clean off grime makes rust proofing totally unnecessary especially with aluminum. The aluminum may corrode I suppose but the useful life if the truck will be long gone.

Had a Chevy Avalanche with 144k on it and I live in west Michigan with rotten salted winter roads. I washed it at least every month in the winter and had zero problems.

Very curious to know what others think.

Just had mine done last week, let them drill and spray away. The locations of the holes they put are very well hidden but this is based on experience of business. I saw no harm and only benefit to have them spray inside all interior panels. There was already a thread discussing the Krown oil to have no issues with aluminum and the sealers. If I was only going to keep the truck for 6 years max, then I would only have the under carriage done.

This question is going to be really more like the "when to change oil threads", likely only going to be a waste of money/time/product that only affects the actual truck owner.

My last F150 didn't last 3 years before rust starting showing up and also in MI, bottom of doors, rear bumber edges and both cab corners so I'm a little gun shy and she was washed all the time.

I had a 2007 Xterra in New Hampshire from 2007-2013, put 100,000 miles on it up there
then moved to Florida where I did another 10,000 miles from 2013- 2016
never did i ever put a rust proofing on the frame or body
I just washed it 2-3 days after the snow storms to get the salt off
when i replaced the suspension in 2013 after moving to Florida not 1 bolt broke, the only thing that needed attention was the hitch, took it off removed the rust and old paint, repainted it and put it on
