Are vehicles almost rust proof now?
If it's the rust proofing I use, (Rust Check & Krown) it has to be applied annually to keep up the warranty on it if it's a new vehicle.
I have skipped a year before if we have had a [censored], low salt winter but most of the time I have it done annually.
It is still popular up here, or at least in my neck of the woods, but like everything else vehicle related this day and age, I think most people are uneducated about it and with the benefits it provides.
I had a long waiting time waiting to get my wife's car done at Krown last November but hardly any wait at all at a Rust Check place just around the corner.I am not saying Krown is better, that is an ongoing debate, but I believe most that have used the Rust Check place know they do a less than stellar job. I will be getting both vehicles done again this July/August as the summer time is the best time to get them done as the product creeps and gets into all those nooks and crannies a lot better when it is warm/hot out.
I've used Rust-Check & now use Krown. Krown came about when a group of Rust-Check dealers dissatisfied on how the franchise was run created it. It's 99% the same liquid, the 1% change was needed to overcome patent laws. It's by far the best rust inhibitor around. Corrosion protection has come a long way at the manufacturing level, but the biggest problem we face today is electronic oxidation, Krown will protect against it, I have a 2001 Subaru never had any electronic problems & a 2008 MB also without any. I don't let them drill and only have sprayed the underside, trunk and engine bay, solely for electronic protection which is the Achille's heel of today's cars. Cost to me ca$80
I wouldn't necessarily nor conclusively say Krown is the best. Both are good products and the only tests I have ever seen were their own showing how great theirs were against the other guys. I don't recall seeing any independent, unbiased tests anywhere, but I guess it's time to have another look.
Like what has been already mentioned, the application from the applicator (worker) is the most important by far. I use to go to a guy on Bloor Street here in Oshawa who did an amazing job using Rust Check. I use to do this myself so I have experience, but after hearing about and watching this guy, there was no way I could do a better job doing it myself, and I'm anal. He was that good and that thorough but unfortunately just a couple 2-3 years ago now, he sold his business to Monroe auto glass and the kid they had doing it was in way over his head!
I also went to the Krown on Somerville (Russett address) back when I had my 09 Sierra. After it was done, I brought the truck home and couldn't believe all the dry spots I seen! I promptly took it back where they regretfully sprayed a bit more here and there, but that was the last time I used them. New owners now, and it is where my wife's Impala was done last November. I heard they were good so I gave them a shot and I'm glad I did. They also, imo, did an excellent job so that is who I will likely continue to use.
I believe my wife's Impala was $135 as well? I think my truck was $150-$175 at Rust Check?
The smell only lingers for a few days and it is far from putrid, and doesn't doesn't smell bad at all, imo.
