I have this in my files. As I recall lots of list members think making this
stuff in your kitchen is
dangerous.
Here is a recipe for home made "Waxoyl".
It's an old fashioned rust treatment / undercoating:
2 1/2 quarts turpentine
12 oz. beeswax / candle wax / maybe paraffin wax ???
1 quart light machine oil
With a cheese shredder, cut the wax into the turpentine, stir until the wax has
dissolved,
(takes a long time; you can use very low heat (a warm room) to aid but be
careful)
and thin with the machine oil to a brushable / sprayable consistency. Apply
liberally.
You can use a hand spray bottle to get into closed-off sections if you have a
small
access hole.
Please be sensible when you make this stuff; don't go breathing the fumes
or applying heat and burning down your house. If you have any doubts about it,
err on the side of caution and just buy a commercially available product.

Rust prevention Waxoyl vs others --- from the Morgan List
===========================================================
The following from "Practical Classics". They tested many of
these cavity waxes for their UK readership in the October 2000 issue.
Factors tested were;
Penetration: The important ability of the product to fill tiny cracks
and cavities. Cavity measurements were made. 2 points for perfect
Adherence: The degree these waxes adhere to metal and prevent moisture
entry. Bare clean metal, rusted metal were subjected to salt spray at a
45 degree angle for 500 hours.
Shrinkage: many waxes are heavily cut with solvent, as the solvent
evaporates the coverage shrinks and cracks exposing the surface it is
supposed to protect.
Self-healing: The ability of the product to heal itself after inevitable
scratches.
PRODUCTS
Dinitrol: Excellent all rounder. Panel came out as perfect as it went
into to the salt spray. Lost only 1 point for a tad less penetration
than its rivals. Highest score. 13/14
Plastic Padding "Cavity Protect" (can liquid): Excellent performer but
poor on self-healing properties. 12/14
Plastic Padding "Cavity Protect" (spray): Slight cheaper than Teroson's
aerosol and a better performer. Lower score than its canned brother or
Dinitrol. 11/14
Hammerite Waxoyl: Best known of the bunch. Poor performer. 8/14. No
penetration whatsoever..as soon as waxoyl hits a cool surface it sets
without seeping in. Super self-healing properties though. No visual
signs of shrinkage after the 500 hours but was the only product where
saltwater penetration was detected. By far the least expensive of all
products at 9.40GBP per 2.5 litres.
If wax filling is your protection choice, the article suggests the
following;
- Do not wax-treat before painting. Wax is almost impossible to remove
completely and it will play havoc with any paint applied after.
- Try and treat your car in the summer months, when there is the highest
chance the cavities are dry. If not, you will be sealing IN the
destructive water
- Always follow the manufacturer's instructions as to pressure and
temperature.
- Unless treating brand new metal, use a degreaser and then a rust
converter before using a wax coating. (See Neutra 661, Owatrol and
Dinitrol RC 800)
