6 Months, Diesel Mechanic. I know where we powdercoat our frames at, we do not undercoat Heavy Duty trucks, or at least the ones I work on. Oh and Heavy Duty trucks are usually dead before they have time to rust out. Its not common to work on something older than 96. Nut again their powder coated so they are usually set.
I dont have the time or the resources to disassemble my body off the frame to do that. I work nights, dont have the time to try and hunt someone down to find out if they know a place to get undercoating, and NOT a spray can of Duplicolor heavy paint .
Salesmen have all the time in the world to get connections to everything, not mechanics or at least mechaincs that actually work.
I just figured it was easier to ask the masses who modify their vehicles, and tow rigs. If I knew it was going to turn into a pissing match I wouldnt have bothered. Its sh!t like this that makes the forums a bad place to get any info anymore.
Oh and let me put it simpler words for you. I dont want an opinion on how you feel about under coating. If you had a reputable business in mind that you or a friend have experience with, THEN an opinion on said company would have been nice. Thats all. I am not trying to personally attack you. Just keep it constructive. Thank you.
