Hi, I'm new to the forums, I was wondering what is the good way to rust proof my bmw. I looked at undercoating and many forums said it doesn't help that much and makes big mess. I live in Ohio, and I am will to drive within Ohio or PA.
Thanks in advance,
Frank
Rust Proof My BMW
If there is rust then blast/grind down to metal and por-15 (epoxy) it, then if you want sound deadener or undercoating use secondskin spectrum

It has many additives for antirust and is suppose to bond very well so it won't fall off. I am in the process of cleaning the whole bottom of my car then sanding it then applying a layer or two of it. My car is in pieces so why not.

The Firewall goop looks like what I need. Do you know if it will hold a paint over coat ?Badger wrote: secondskin spectrum

sounds good, ill definetly call them tommorow, thx for your time. If anyone has anything else they would like to suggest you will be really helping me. I have looked this up already and only seen a rubberized undercoating and now spectrum. I wont be doing the antirusting till summer as my car is being stored for winter. So i will be comparing different ways to antirust.
thanks in advance,

Update. After viewing several solutions, I have come up with the best solution to anti-rust & de-rust your car for many years to come. It is a bit of work, but I believe it would be worth saving your cars body(especially since BMW engines will outlast the body twice-fold 
)
1. Scrap and sand all of the rust on the bottom, and anywhere else you want to de-rust & anti-rust. It doesn't have to be completely bare but get most of the rust off. ((I'd recommend to do this before you get a new paint job if you have rust on besides under the car))
2. Buy some POR-15, it is a rust converter and anti-rust. Its like paint but will protect any further rusting. Read up on it at http://www.por15.com/
3. Get a rubberized Undercoating over-top the POR-15 so no moisture can get past the rubber, and if it does the POR15 will stop it. The rubberized undercoating will also protect the por-15 from getting chipped,nicked,scratched off by any rocks or anything.
4. I think you should check the rubber undercoating every year and replace what is gone do avoid having to re-apply the por-15. Only because por15 is pretty expensive.
NOTE: Don't get the rubberized undercoating if you are por-15 the part of the car that gets painted.
Thanks for all your help and suggestions, the spectrum guy told me about por-15, and por-15 recommended getting a rubberized undercoat to protect it.

It is not a rust converter and it is not "like" paint -- it IS paint. It's moisture-cured urethane, which we recently discussed here.dermauser wrote:2. Buy some POR-15, it is a rust converter and anti-rust. Its like paint but will protect any further rusting. Read up on it at http://www.por15.com/
