I definitely wouldn't get a module, but Krown absolutely.

 

Don't get me wrong, I'm a big believer in Krown.

I have no problem with them drilling the holes. I had my 2010 F150 sprayed each year by Krown and it looked great 6 years later when I traded it. I understand that aluminum can corrode and that oxidation is the same cancer to aluminum as rust is to steel.

Krown is a petroleum based product and it's the foam and adhesives that you mention that concern me. Nobody can give me assurances so far that the Krown product (or any other spray for that matter) won't cause damage to these materials. I'm sure the actual aluminum would be just fine with the spray.

Even their own website states that Krown is designed for steel, but it can't hurt to spray aluminum with it. But they don't address the adhesives and foam and the materials that may be present in the aluminum built body.

I'll be getting my new truck sprayed for sure, but I'm still undecided whether or not I will get a full spray (holes drilled and all) or just an undercarriage spray to protect the steel frame.

The ONLY downside to Krown IMO is that it drips and smells bad. My driveway is all stained where my truck sat as I park it in the same spot each night. Of course it drips like mad right after being sprayed, but I found that it kept dripping all year with a few fresh drip spots on the pavement each day, especially in warm weather. They say it washes away, but it really doesn't. I tired scrubbing the driveway with a brush and cleaner but that doesn't work. Then there's the smell... I could still smell it burning off under the truck or in the engine bay all year round, worse on warm days when sitting it traffic. That smell was annoying at times.

However, it is still the best rust protection as far as I'm concerned.

 

I understand what you're saying. Krown is basically like a vegetable oil and its environmentally friendly/biodegradable so I can't see it hurting anything. It's also been around for a long time and is basically the best stuff out there and has the track record to back it.

 

LOL yeah it's messy, but those drip spots do eventually disappear from your driveway. The first few days I usually try to park on the street. The warmer out the better for getting rid of the excess stuff.

 

Yeah, they are the best... I definitely agree. I guess I'd feel more comfortable a few years from now after they get some runtime on spraying the aluminum vehicles. It's still fairly new to them I think since the F150 is the first mass produced and popular vehicle to go all aluminum.

 

There must be other makes out there that use or have used aluminum over the years and been Krowned?

Either way I'm not concerned about it. What concerns me are those rivets used to connect panels, and the water containing foam used between those rivets. Been there and the paint will start to bubble underneath where the wheel well/quarter panels are put together. I was going to repair it but a body guy suggested I just get it sprayed and that will stop it. I had it Krowned and the bubbling stopped.

 

I get my truck on Tuesday and will be taking it in the following week to Krown. I was thinking Ziebart this time around but consensus says Krown. On my 2013 f150 I took the rust module off and if I decide to install it takes 5 minutes.

 

I was on the fence as to have my truck drilled or not, with the same concerns about the adhesives. I ended up letting them drill the body. I'm pretty sure Krowns claim to fame was how their product doesn't damage rubber trim and seals like some of the other oil based products do. The owner of the Krown that did my truck had no conserns at all. He's a car guy and I'm sure he must have done some homework when he heard the highest selling vehicle in the world was going with an aluminum body. I was willing to chance it!

 

I wrote to Krown Corporate to ask about this and my concerns. With their permission, I'm posting their reply:

Thanks for taking the time to contact us. We have many customers with similar questions and we are happy to say there are no issues. We have been treating the new aluminum bodied F150s for almost two years with no problems. We have been a recommended product by the Tesla club of Ontario for nearly a decade. Tesla has been using aluminum bodies for a long time and we have had good success in treating them with no negative impact.
We will be happy to treat the entire truck or just the underside – whichever you decide but you have nothing to worry about as far as damage is concerned.
We hope you enjoy your new truck!
