Waxoyl-ing my S3 - any advice?

[The Doctor]

Hi guys, I'm planning to Waxoyl my 2003 S3 over the Christmas break. I know the car is/was under-sealed from the factory but over time I'm sure this wears off/gets scuffed off as repair/servicing work is done & bits & pieces get caught on the floorpan. No point keeping the paintwork nice & shiny if it's rusting away underneath.

My intention is to seal under the car itself (avoiding exhaust/brakes obviously), behind the wheel arch liners & within the doors/rear panels.

A few questions before I start though;

Anyone else done this?

Will the Waxoyl affect the original under-seal? Wouldn't have thought so but worth checking.

What's the best way to access the doors/rear panels? Will I have to remove the interior trim or are there any cunning access points (eg. bolt holes etc)?

Cheers.

Car was galvanised from the factory so shouldn't need it, however it might just be worth checking if there is any exposed metal around the jacking points etc.

As above, it shouldn't be required. Thats a job for the likes of Landrovers etc, not modern Audi's!

agree, i just check the underneath of mine about once a year - years on and still looks mint...

jacking points are the only areas that have been scuffed but even the bear metal there doesn't seem to rust - didnt know they were galvanized.

OK then, I'll have a good look around underneath & decide what to do. I'd have thought that over time the dreaded rust would appear, but if not then I'll save the cash & avoid the hassle. Cheers!
