Krown Rust Proofing or Fluid Film?

fortunately I live in the desert, sheet metal does fine, we cant keep interiors intact here. jim

 

I’m using Boeshield and it works well, but have never tried the others.

Heard good things about Sharkhide too.

everybody and their brother's mother uses Fluid Film around here

I lease my vehicles so I don't care lol

 

My '05 Chevy pickup was rust proofed by previous owner, so its one of the few, here in MI, with no rust and rocker panels intact.

 

I typically keep my vehicles for 7 - 10 years. I don't rustproof them. I've lived in MN or WI since 1978.

I haven't had rust issues on any of the new vehicles I've purchased in that time - 1979 Chevrolet Caprice Classic Landau, 1979 Pontiac Grand LeMans, 1984 Renault Encore, 1998 Pontiac Grand Prix, 2000 GMC Jimmy, 2006 Pontiac Torrent and a 2014 Chevrolet Sonic.

What I do, do, is wash them regularly during the salt and snow season.

 

I'm not near the rust belt but I used Fluid Film to coat some new bare suspension parts and it's kept the surface rust off. I can't comment on the other products.

 

I used both Rust Check and Krown. When I tried Krown on my 87 GN, it worped my front air dams. So if you have any plastic, Krown will soften it which you don’t want. When I complained, they said it was Rust Check’s formula that did it. I’ve used Rust Check for about 15 yrs on the GN witout problems until I decided to try Krown. That’s the 1st and last time I went to Krown.
