Navi / Expy door rust

Having had my door seams repaired under warranty, surprise, surprise the corrosion seems to have returned. I hence decided to take another approach.

When I lived in the UK all the restorers of classic autos used a product called Waxoyl as a rust proofer, corrosion inhibitor for seams. It is a light weight mix of oils, waxes and corrosion inhibitors. I purchased a can which comes with a pressure spray and injected all of the seams via the drain holes with the included extension tube. You just slide this in through the drain hole all the way to the end of the door and then withdraw it slowly while squeezing the trigger on the applicator. What is good is that you inevitably apply too much evidenced by the amount of excess that drips out of each drain hole. This way you can be reasonable confident that all of the seam has been treated.

Time will tell whether this inhibits the already present corrosion but I have had great results on a 1965 Rover which I restored in 1990 and treated with the same product.

sounds like a good idea. Are the drain holes still functional or are they clogged with the rust proofer?

They are still fully functional. The Waxoyl product is supplied with a very low viscosity (like chocolate syrup), which makes it so good at creeping into seams and also ensures that it doesn't build to any great thickness, hence avoiding plugging of the drain holes etc. They use white spirit to get it to that viscosity and then after application the white spirit evaporates over a period of about 2 weeks and the coating dries to a more solid like waxy consistency.

If you can't find Waxoyl, there is a similar product used in the bicycle business. Here's a link to a place selling it that I found doing a quick search:

A friend of mine was in the frame business and told me about this stuff years ago. Works great.

For what it's worth, I've had great luck with a product called POR-15 which is made here in NJ. I've had great success with it on my floor panels in an old Wrangler, and in the door seams of many of my old BMWs. Worked like a charm.

Cheers,

Will this stuff actually stop or reduce expansion of rust? I have the same problem on my back doors of our 98 Ex. They are not that bad yet and if this would slow or stop it, it's be great. Looking forward to hearing more. thanks

Here's a link to their site:

I've had really good luck with their products myself, so I hope this helps a little.
