I had GuardX treatment on my
NHB ES, cost £300 for the exterior and interior treatment. Friends in the paint trade said it was worth having. Still not convinced about the exterior protection. I still have to spend alot of time getting rid of the water marks, but looks ok when I have finished. Next time, I would spend the money on good quality products, possibly Maguires. I have read several forums on car polishing and it seems to be the only way to go if you want a deep shine to your
NHB, which is what I want. At least the wife and kids know what to buy me for birthdays and christmas, no more excuses that I am hard to buy for.
