Did you rustproof your A3/S3

[AnthonyA3]

I never rust proof but I love her so I'm thinking about it. Any point getting under the car sprayed or is most of the metal covered in plastic.

On a side note I keep my cars till they die

Most of the aftermarket processes only serve to trap dirt and moisture. A car from the factory has more than enough rust proofing to last a lifetime if the car is properly washed often. I take it by your second comment that you have no problem keeping them clean. If it were me I'd pass on the additonal rust proofing and just care for the car properly; and touch up any dings or chips as you go.

^+1 plenty of plastic covers and the pinch welds are coated in wax/rubber from factory. Only thing exposed really is the suspension and who doesnt have coated coilovers anyway😎

Plus I think the steel is galvanized or at least some of the VW cars were

I did the same thing to the undercarriage of my 2006 Tacoma that I owned for 10 years- Sprayed it down with an Amsoil product called MPHD. It spray's on and dries to a light transparent honey color. I'd do it once a year, and the frame of my truck still looked like new when I sold it. Great product!
