Jeg vil tro at bilene er galvanisert og da er det ikke noe vits i tectyl. vil jo alltid få noe rust på skruer og diverse.. Hadde en 1990 mod Audi som var galvanisert og ikke tectylbehandlet. Ikke noe rust her utenom på skruer og litt overflate rust på lenke armer.
Tatt fra Mini2: "Done a bit of research... The car is basically made from formed sheet metal. To protect it from corrossion, the whole body is dipped into an electrocoat bath, and this is where an electric charge applies a protective paint to the body. Then a PVC resin is applied to seal body seams, and this is for waterproofing, sound proofing and vibration (yes, vibration!). The car then has a primer applied to protect against chipping and then has a total of 6 coats of paint before a 'clear coat' is applied for hardness, depth and durability.
Looks like this process provides us with our 12 year anti-rust warantee! Dont think we will get any problems with rust for years to come."
