Rustproofing - what works best?

[IPF]

Suppose one brings a nice, "rust-free"(? ) West Coast car to a piss-poor climate like Western Europe's and suppose one wants to drive it more often than those scant 3 days a year that it doesn't rain or snow.

Now how would one protect an early 911 from (excessive) rust, other than keeping it dry and garaging it? There appear to be many options indeed :

- Dinitrol: apparently a classic, both for cavities and bottom. Reported to reek 'n leak for ages after treatment

- Caprotech RX: 5, 7 and 10, for cleansing, cavities and bottom respectively. Reported to harden more than Dinitrol, reducing reek 'n leak

- Waxoyl: don't know the details, but it's a waxy substance for all over/in

- etc.

Does anyone have experience with any of these? What does and doesn't work? What are advantages/drawbacks? Self-applied, or outsourced? If the latter, roughly at what kind of cost?

POR15 works quite well.

I've also had good results with Loctite "Extend".

Good luck,

POR15 is some really tough stuff. Just ask anyone who has spilled some on the garage floor. You can't go too far wrong if you clean all the surfaces really well, prime any bare metal, apply a liberal dose of 3M seam sealer to the deeper nookers and crannies and top coat with POR15.

My 73 car had Dynol, a Dutch product I think, applied to the underside when it was brand new. It has spent its whole life in New England and though it's never seen winter, it has seen wet weather. I have been gradually removing the coating (easy with mineral spirits), and what's underneath is remarkably well preserved. You have to make sure you're not applying it over rust, however.

Waxoyl is good and is big in the UK/euro. plenty of places will apply it.

Everyone Here in Ontario tend to swear by and recommend Krown Rust control products and service. We have very heavy salt use in heavy snow conditions in Canada and they seem to have something special that works well. www.krown.com

Hope this helps...

I would look into general aviation corrosion prevention products. They use narrow wands that are used to spray product inside wing and fuselage cavities.These cars rust from the inside out!

Allright,

Thank you for your reactions!

From them, I see there are as many opinions and experiences as products out there. Very interesting to also see a certain geographical preference emerge:

Anyway, to do at least something about rust appears a broadly supported idea!

Driving the car in the rain isn't going to hurt it, if properly cleaned and stored. You would be crazy to drive it when there are any chemicals on the road, nothing will protect it from that.

And it was an east coast car until it came to California about ten years
ago. It has no rust that I have been able to find, sweet. It does however
weep out of some places and needs occasional cleanup (I use 3M adhesive
remover), I consider this a small price to pay.
