I am beginning to sound like Columbo but “just one more thing” I am not taking the paint guard option from Honda as I applied the “Diamond bright” paint guard myself to my last car and it worked very well over the years, it cost a lot less than Hondas and is supposedly exactly the same formular as "Diamond bright". However I understood that using any other polish on top of this especially the cleaner polishes that contain silicon can neutralise the paint guard. A friend of mine uses the Jeeves polish from one of the shopping channels on his old car and I have never seen such a deep polished finish before it is brilliant for glass and cleans the plastic trim (like the Civics) to look brand new, but I am apprehensive to use it if it interferes with the paint guard. I would be grateful for any advice!!!
