Rust prevention

endo · Sep 21, 2015

So what are your guys opinions on coating the underbody with POR15. That is the plan I have. I also want to use the POR15 putty where body panels join together. Does this sound like a good idea. Might also consider a standard undercoat after as well.

Also what can I do on my own to prevent rust on bottom of doors.

Also might consider rhino lining the lowe part of the truck body at some point as well.

Thanks guys

POR15 is an outstanding product. While POR15 epoxy putty is good stuff, I'm not sure I would want to use in the seams of adjacent panels, turns hard as rock. You can choose to undercoat using either POR15 rust preventive paint or POR15 rubberized undercoating / or both

I know several people that reside in Colorado that undercoat with Fluid Film because of the calcium sulfate they use on the roads in the winter, POR 15 is by far better for longevity plus can be painted over rust

Paint protects against rust and a sealant or wax serves as an extended protective coating, just exactly what condition are the lower door panels currently in ? Condition of lower panels would determine necessary maintenance steps required (prep) - also, POR 15 makes a product for bed liners that can also be used for spraying lower rocker panels if desired....

Pics of panels would be helpful....

No rust is showing at all on any body panels as of now. I'm assuming the truck has been garage kept so my goal is to give it a long lasting rust prevention now rather then wait.

Unless paint is compromised and bare metal is exposed , it's not going to rust. Using a undercoating to protect undercarriage like you plan on doing is an excellent idea, other than that, no need to worry.

Apply a coat of Collinite 845 wax every 4-6 months or apply a sealant every 6 months to year depending on choice and you'll be good... of course, use any wax of your choice, just mentioning the 845 based on price, ease of use and longevity. IMO nothing on the market can touch it when comparing those 3 factors. While 845 looks good on all colors, it outperforms on whites.

Rinse out your wheel wells on a regular basis! Pull the tail light and thoroughly rinse out between the inner and out sheet metal before your quarters rot from the inside out.

Por15 served me well when I lived in a rust belt area. Painted the whole underneath of my old ride with it.

Another option is Chassis Saver. Much cheaper than por15 and works good also.

Soda: a very effective means to combat rust. Soda is rubbed into the surface itself or in dry form, or as a specially prepared solution.

My friend who owns a body shop says he uses Fluid Film. I haven't tried it yet, but I also need to do some kind of undercarriage rust prevention for the winter.

I'm having the full Ziebart package done in 2 weeks.

Up here in the rust belt Buffalo,NY the best thing is having the vehicle "oiled" rust proofing like rusty jones. It seeps into the seams and keeps them protected. I had my 03 F150 done twice and doors and rockers were still good box was shot however they recommend having it done every year here but doubt you would. .

The standard old fashioned rubber or tar undercoatings don't work up here, really think they hold moisture in. Its the seams that really rust flat sheet metal is fine. The oil is stickey almost like cooking spray.

Fluid film once a year. Safe on everything. I have a 1997 ram virtually rust free. Just applied it to my 14 in January we I bought it.

used Krown when out east but now I do not need their services. Firstly I do not drive in the rain or snow, hell it does not even go out when the roads are wet. Oh my toys received Krown out east even though they sat all winter and never saw wet roads in the summer but the humidity levels are through the roof, the other day my personal at home weather station had the humidity at 19% all afternoon. Nice way to save several hundred dollars ie not Krowning all the toys/vehicles.

^ Yup, I use Krown on all my vehicles. Stuff is worth it's weight in gold up in the north here.

Would be nice to live somewhere where it isn't needed!

Has anybody used boeshield t9? We've used it on some bare metal applications at work and its been pretty impressive, was thinking about coating the underside of mine with it.

I am using Fluid Film also. The plan is to apply twice a year October and April.

Living in the RUST belt when my new truck 2016 ram 2500 arrives end of march I will be headed out to my Krown rust dealer to get it fully rust proofed

Krown annually here too, with some Fluid Film touchups on the suspension throughout the winter.

I was using fluid film on my old truck but I think I'm going to switch to LPS 3. Read some good detailed blog posts showing it outlasting FF. Here is one of them.

Do you have to keep re-applying the Fluid Film or will it last?
Thanks.
