"ZBart"

[crewcabfred]

i have torn apart 3 different trucks that were z barted and the spray pattern of the coating they used was only about a 4 inch circle behind every hole that was drilled, the vast majority of the sheet metal inside never even saw the coating.     That of course was due to the poor workmanship of the person spraying. Regardless, all the trucks were super rusty.    I do live close to the gulf coast however, and theres nothing you can really do to stop salt air.   Our local zbart has changed hands so many times because it is so ineffective.  It is notorious down here for being a scam. Really, unless they are getting every little crack and crevices, the places where the rust really is a problem, how is it going to work?  Also, if you are spraying a used vehicle, the coating is going to be sprayed over dirt, sand, moister, or whatever is caught up in the seems. It will then just hold those rusting agents in. My opinion might be biased because of my circumstances, but It just seems to me that all you are doing is paying somebody to drill a hundred little speed holes in your door jams...

I've always wondered if a person would know on a brand new vehicle what would be the primary rust out spots. IE 88-98 with the cab corners. Would someone know that and know where to spray fresh out of the factory?

Anywhere that moisture can be trapped and oxygen can get at it is susceptible to rust. Your best bet is to neutralize the areas and then protect it with one of the bazillion products out there. Por15 followed by an undercoating or similar will provide good protection.

I don't think I'd go the Z-bart route again. I had that truck for 5 years and the smell never went away. The little yellow plastic plugs with the Z-bart emblem were everywhere.
