I decided to spray Waxoil on the front and rear suspension to keep the underneath of the car looking good, and to help with any future maintenance and repair work that might otherwise involve battling with corroded and seized parts. There isn't much paint on the suspension parts, and some of the parts (the anti-roll bar drop links on the front for instance) are not painted at all. The rear suspension is probably more important than the front because it takes the spray from the front wheels. It's not uncommon for the rear torsion bar to get corroded and fail on small front wheel drive cars like the UP! My car has only done 500 miles so it's relatively simple to do it now. I hired a morning's access for hydraulic garage lift from a place in Gravesend. It only cost £60 and they were great. I bought 2 tins of Waxoyl spray from Halfords. The local VW dealer wouldn't do it because they said it would invalidate the warranty. I suspect the real issue is they just didn't want to do it because it's potentially messy. I used a lot of newspaper and put it on the floor under the car. I guess my dealer did me a favour because I saved a lot by doing it myself.
