I'd like to get my car rustproofed and deadened, does anyone have any experience with getting it done with deadening in the door? I can either get the rustproofing done and then clean the areas where i want to lay the deadening or deaden the doors and then have them spray the treatment after the fact.

I know i can ask the tech not to spray up in my door but that sort of defeats the purpose... Any suggestions?

Putting deadening over the rustproofing will seriously diminish the effectiveness of any vibration damping.

What do you recommend i do?

Th deadening should seal out any moisture from underneath, I would personally deaden then rustproof.

Just to make sure I understand why do you want to rust proof your vehicle?

I live in Canada, it's pretty much standard up here.

wouldn't you want to rust proof the outside though. The sound deadening would go on the inside.

They spray inside the doors as well

The rustproofing I know of is oily stuff applied in a mist that covers all the surfaces it reaches. You would have to clean it off with a solvent where you want to stick anything to it. Stick deadener on first is my vote.

I have been curious myself about how to treat the cut areas on the mounting hole to prevent rust. Just paint will do it? or any special paint or primer needed for it?

There is a paint that chemically transforms rust into, well, a paintable non-rust-ness. For a fresh cut, a nice coat of rustoleum and I've never had a problem. On the outside, in nonvisible areas, I self etch prime, paint, then put bedliner over that (did this with my truck). As for your rustproofing, deaden first. It is highly unlikely for anything to rust sealed by deadener (keyword, sealed).

Thanks, Sirb00m


As far as the OP, I agree deadening the doors seals and prevents rust, the issue is having to put a layer on the inner door facing the outer door, and another layer over the inner door facing the door card.

Also on the outer door, some steel bars may be making it even harder to deaden.

When deadening, it is critical to not leave gaps or bubbles where water can rest, usually at edges and placing it over areas where those gaps and pockets can be created.

What I would do is, deaden the inner door and outer door as much as possible without leaving gaps and pockets for water to rest, then Rustoleum or bedliner coating over the inner door facing the panel and all areas not covered by deadener

Or deaden with the 25-40% rule and paint or coat over the areas not covered with deadener.

The rustproofing im referring to is for preventing rust/corrosion caused mostly by the salt on the roads

sorry I was asking about products other than rust proof ones, as it was mentioned using rust proof products before deadening may not be ideal since they tend to be greasy or oily.

It was also mentioned that the interior of the doors may not rust compared to external stained steel being exposed.


Most expensive door speaker drivers, are made of aluminum, stainless materials, terminals, nickel, treated copper, brass etc, some areas may rust but not the important ones that may affect the driver's performance, assuming you were concerned about the speakers and not just the doors.
