Hi all,

I'm planning to take advantage of my car's current "bill of good health" in regards rust and get her waxoiled this summer.

Has anyone in the group tackled this job themselves and can offer any pearls of wisdom?

Essentially:

1 - Where to apply?
2 - How to apply?
3 - How much to apply?

Thanks all.

Hi Pete

For where, you want to put a cavity wax into the sills. You can access through the holes for the carpet/sill finishers and if you have a 500L the outside holes for the finishing strips. If you don't have these, you'll need to make some bigger holes inside and then place blanking grommets in them.

Inside inner front wings and outside bulkhead where the door hinges are. Easily accessed from the front underbonnet.

Inside the doors at the base, easily accessed with door panel off.

Inside rear panels. Optional this one as mine was fine here, not even any surface rust.

Rear inner wings. Accessed by removing rear light clusters and the blanking grommet higher up inside engine bay.

I also clear waxed inside the front panel. The underbody can be covered with a good quality underseal.

I used dinitrol 3125 for cavities and 4941 for underseal.

cheers, Steve

Great, thanks for the advice Steve, much appreciated.

....and do it on the hottest day of the year, if you can.
I used Waxoyl as it's cheap and readily available, and found that a 1 litre Schutz-sized can was more than enough to be thorough. You really need an airline to atomise it properly.
I always keep an aerosol can of wax handy (I get it from Toolstation) and whenever I'm under the car, (quite often recently!) I inject extra wax in nooks such as the corrugated bit at the back of the body-lifting points at the rear or inside the supports under the front floor.
Last summer, I cleaned up the inner wheelarches, especially around the lip, and I gave them a coat of Waxoyl-impregnated underseal. It's smooth, not that old-fashioned gritty stuff and boy does it repel water. I'm planning a re-application if this year ever warms up in Scotland.:bang:
