Line-X Rustproofing/Undercoating

So I've read a little bit about this stuff, I tried searching on here to see if anyone has done it but couldn't come up with anything..

Apparently it's the only undercoating OEM endorses? Has anyone gotten their truck undercoated with this stuff? If so how well does it hold up? Was it expensive? Did they coat the inside of the frame?

I'm looking into it, as my 97 is virtually rust free with only 102K miles on it. And most likely won't be rusted out by the end of the 15 year warranty period!

 

Line-X undercoating? I've never heard of that...I thought it was a spray on bed liner. Got any links??

Yeah that's one of the things I read. I saw some pictures of a Dodge that had the whole underside of it done, body panels and all. I just wonder if they spray the whole outside and if they can spray inside of the frame.

 

Old thread but good topic. From what I've read, bed liner coatings don't make the best rustproofing because they tend to chip out over time...which can let water under the coating. That's not good. Rust tends to develop fastest when moisture is allowed to enter via surface breaks, cracks and crevices...like around welds, joints, flat spots inside the frame and wherever else sand/dirt/salt can collect. A flexible barrier that 'gives' when hit or scraped but stays sealed is a better bet. I suppose that's why lots of people find that annually coating their frames with oil or grease works pretty well for rust control...it doesn't crack. Pretty messy, though.

 

I know this is an older thread but I have had great luck with a
product called WaxOxy. It consists of beeswax and a rust inhibitor- oil .It stays
soft but not sticky as to grab dirt ect. Best coating results ive ever had. The only
site ive found it at is www.roversnorth.com . I used 4 500ml hardwax cans on my
02 tacoma and if touched up every year your truck wont rust . Im not a salesman for
this stuff , it works great and ive tried all meens of rustproofing.

 

I'd like to see what DIY rust protection potions folks are using. I've heard of a 'home-made' waxoyl made of paraffin, ATF and mineral spirits. Even a thick layer of car wax (pasted or sprayed on, not rubbed off) might work as a passable seasonal winter frame/undercarriage protector. Oiling the undercarriage works, but it's wicked messy. There should be a thread on this to discuss ideas...there are too many perfectly good Tacos rusting away to ignore it.
