I have an Aurion AT-X 07, purchased recently ex-Toyota "pool" car, only done 13,200klms, warranty runs out 06/11. It's the family sedan at present (until I take it over next year when the wife gets new a car !), so my question is, has anyone or do you recommend Scotch Guarding the interior ? Say the door trim only ? Appreciate your feedback Hi I have used Scotch Guard since 1974 and still use it, its great. Don't skimp, give it a good coat. If you spill something on the seat it just wipes off. Or at least it has for me. It forms a waterproof coating. I've also used Armourall For years and have no complaints. Current car is a Vienta Grande with leather seats etc and so far have used Meguiars Gold Class and Autoglym but have not had time to make an assessment.
