Undercoating
 

Hi all,

I have a 2013 A4. Is it worthwhile to have it uncoated before the winter, and what companys are good?

Thanks,
Dave.

Not out Ottawa way, so i cant help you on places to go for the service.

However, getting it done wont hurt; salt, sand, gravel, with constant moisture is a vicious combo.

I have looked into this extensively on many forums...
Your car is a brand spanking new car!
Audi are among the best rated in the business with galvanized steel, super well protected backed by one of the most extensive rust warranty to boot...not like my wife's 2003 Mazda protege lol

If you drill holes it will void your warranty, and some oil based ''rust protection'' will damage any rubberized piece. It is a HUGE industry and they push it everywhere however do your homework as well

Best advice is to have it waxed, protecting the paint twice a year and wash it/hose it every week especially the undercarriage and you will be fine, trust me

Experts suggest that if you must do it wait at the very least after your warranty expires
My 2 cents anyways

1)Google "galvanized steel" (should mention zinc)
2)The majority of our underbody is covered by plastic anyway
3)It does void the 12 year rust/body warranty even though there’s no real way for them to prove you'd had it done (unless the place drills holes)

Conclusion = Save your $$$.
The ONLY place I would trust would be KROWN, since the ‘’add on’’ components such as sub-frame and suspension might benefit from a treatment.
