+1 for Trainyard Auto if you are in the Ottawa area (there is another shop in Little Italy - Holiday Auto that is also decent). Trainyard did mine, and my Oxford White was the third 2016 F150 getting sprayed there today. I have been rustproofing my vehicles for years and much prefer Corrosion Free. However, it is all in the application, and they are solid.

 

Thanks for the advice and I do agree, the install makes all the difference. Good to know that this shop is a good one. My last truck was Krowned annually, and I do believe it made a huge difference. Has anyone had both? How does the Corrosion Free compare to Krown for dripping black year round?

 

Not trying to start the rustproof debate. Both work and I have personally used both. One of the reasons I prefer CF is that it does not drip all over the place (driveway, clothes). It is a thicker product but still creeps. Some will say that this is the exact reason why Krown is superior, it is thinner. Can't say I agree. Also, for many, the rubber around the doors and hood swells using Krown. I can personally attest to this on my last car. Hated that. Nothing like looking at the hood of your car with the rubber sticking out. Either is better than nothing for the frame and underbody.

 

Wait, what is the difference between corrosion free and Krown? I thought Krown is a corrosion inhibitor? I was planning on getting my truck treated with Krown in October but I don't want the rubber on my truck to swell and look crappy.

 

I've been using Krown for years, and haven't had any rubber seals swell or become damaged because of Krown. I believe Krown actually claims to be compatible with rubber seals. I think I read somewhere that Honda/Acura seals may Not agree with Krown. But personally, I haven't had a problem.

 

My previous trucks (2010 f150, 2007 Tundra) were sprayed with Krown each year since new.

It was great at slowing down the rust that inevitably forms on the frame and axles etc.

Only downside is that it dripped all year long. I would get it sprayed in September and it would still be dripping slightly on hot days the next summer. Plus, it would drip onto the exhaust and burn causing a nasty oil smell. This would occur only on hot days. My driveway is still stained from where it was parked each night,

The only swelling problem I had because of it was the long piece of door weatherstripping that runs along the bottom attached to the body. It became noticeably stretched and drooped between the attachment points.

Krown is excellent at slowing the rust process (it doesn't actually stop it), but it isn't without some drawback. This is my opinion based on using it my last 2 trucks, 2010 f150 and 2007 Tundra.

I still haven't decided if I'm going to get my 2016 treated or not. If I do, it will just be an undercarriage spray. They charge about $65 for it.

 

I hadn't noticed the seal issue on my 06 F150. I don't want to start a comparison war either, but figured I'd ask....

I was asking about the dripping/seeping as I'm lazy and don't wash it anywhere near as often as I should, so the black stains that ooze out of everywhere are always showing. Wondering if the Corrosion Free will be as bad as Krown was for that.

 

in the Fall of 96 I had my mustang GT Krowned the day I put it away for the winter. They gave me a giant peace of clear plastic to lay in the garage under it.
This stuff walks up hill!
Anyways, no rubber damage.
Also to note, it seeps out of everything (handles, seems, under rubber trim, etc) throughout the following summer!! Everytime you wash it, it runs out and leaves oily streaks...not that big of a deal I guess.
