Washing the undercarriage in preparation for waxoyl

Post by **Malcolm** » Sun May 21, 2006 6:33 pm

How does one go about washing, cleaning or otherwise prepping the undercarriage before spraying a new coat of Waxoyl?

Do you need a power sprayer? Wire brushes? A toothbrush and bucket of water?

Thanks.

If it has already had a coating of Waxoyl then it should be a nice gungey
mixture of road dust and wax by now to which I would apply another coat of
Waxoyl. It works for me.

Clean any dirt off with a wire brush.
Only apply the waxoyl when the weather is warm and dry.
Any dampness will be trapped by the waxoyl and cause further rusting.

wait till the weather has been dry for a few weeks jack the car up and simply brush all the dried dirt off the underside- I used a dustpan and stiff plastic brush (with dust mask on!), treat any rust, remove any loose underseal and get any necessary welding done before you apply the waxoyl.

A compressor and a shultz gun makes waxoyl/Dinitrol application much easier!!!
