rust proofing cavities? Options

[rfuerst911sc]

Is there a pictorial or diagram of all the empty cavities on a 914 that can/should be sprayed with rustproofing goop? As I make my way thru my 914 in regards to surface rust cleanup on exposed exterior surfaces I would like to also spray in all empty cavities some goop. So where are all of these cavities? I know the longs but where else? And where are the best places to drill/spray some goop?

Anything that is a closed box is a candidate for cavity wax.

For commerical applications the Wurth Multi-Sprayer is what most high end bodyshops use. It has a plethora of tips, and wands with 6 foot extension tubes.
The wand heads are available in round the corner, daisy and 180.
This is the best applicator ever produced because you can get in just about everywhere. Windshield pillars, hinges posts, sail panel's. It not only sprays cavity wax but also a regular fan spray head for rocker, chips guard's and undercoating. I think it was developed by a proctologyst. Really easy to use because all you have to do is get the tool head where it needs to go and squeeze the trigger while slowly pulling back on the tubing.

On the other hand Wurth also makes Protective Wax. If you have an area that is already painted and sealed this is one more budget minded step in corrosion protection. The PW is what you would see on Porsche and BMW around hood hinges, flanges, jambs etc. It is visible on many horizontal surfaces .It is a great product for after paint seam sealing. Its thin and stays put. This can also be used on gromets, rubber wiring sheaths, and pass-through's that may seep a bit. Those headlamp bucket drain tubes that rust, get some PW!
