Door rust prevention question


NullZwei

Recommended Posts

I just installed new doors and I'm looking for a good product to apply to the inside bottom of the doors to prevent water migration into the seam where the outer door skin lips over the inner structure. What product has anyone had good luck with for this purpose?

I used a spray can of thin rust prevention fluid (not sure about Wurth but in Canada we have Krown, which works well) with a plastic tube attached. The idea is to start spraying in the upper corners into the seam, pushing the tube into the crease. Work your way down, and then along the bottom. Put an aluminium baking sheet under the open door - this will drip for a while. You can then reapply every few years. Some folks may prefer to fill bottom inside seam with seam filler (sort of thin putty that sets up) or heavy undercoating, but I prefer being able to get into the actual seam. Spray across the top inside of the door too. Ideally, all this is done with the door off the car and standing on end. I did one edge at a time and then rolled door 90 deg.

Before doing the above, I would consider applying some seam filler (I think Eastwood has something) along the seam on the outside bottom of the door that faces in to rocker.

Good stuff I have used in the past is a product called Waxoyl. Made in the UK, do not know where to source, but willing to bet places that provide bits for LBCs, like Moss Motors or Victoria British would have it.

In 1997 I sprayed 3M's "rust fighter I" into the (not all that pristine) doors on

Jenn's car. 15 years later, all outside winters, there's no door rust yet.

or just fill a spray bottle with your next waste oil change

and spray where your want - park in your neighbors

driveway over night while the excess drips off!

Sorry for duplicate posts.

I've used Waxoyl too. I used it on all the inside panels, including the nose, on my CS, and it's still there 25 years later. It sets up nicely on vertical surfaces, but doesn't creep as well as the thinner spray. Consider it for the rest of the inside door panel after the seam spray.

is called RusFree--comes in a spray can with a long wand extension. I've used it for years on blind interior panels like your doors with very good results.

If I recall waxOyl is temperature sensitive, mainly to the heat, it can melt.

If Florida with a black car it may end up going out the drain holes over time.

Hi there

I used a polyurethane paint called Rust Bullet http://www.rustbullet.com/ . I first degreased and cleaned with POR15s Marine Clean and Prep and Ready. The PU paint is nice because it requires (molecular) moisture to set so it pulls it from the metal (if any) (apposed to being dripping wet). Also, tough as nails.

I did the same thing to the rockers as the doors, only a lot more so, with

similarly good results...

Lots of whatever 'waxy oil' product you choose, and do your best to try to

spray the entire perimeter.

Most of 'em will let the excess drain out, and that seemed to work great in our case.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
