After 1 year, my car body feels gritty to the touch. Very not smooth at all. I wasnt happy about this so I text Mr.Choong and told him. His reply is that this is normal and I need to shampoo it and do clay bar.

Before doing SierraGlow I was told just wash with plain water, now they want me to do claying?

I wont send another car there thats for sure

what is there to understand?
i wash my car once a week at a detailer nearby my place
always park under shade.

I dont want to be ignorant hence my question
But if you are asking a lay person to know about detailing etc in order to keep this Sierra Glow job looking like day one, I think then better dont spend money on this.
Its suppose to be easy to maintain.

Anyway I am not looking for a solution from Mr.Choong. I just want to warn others. If they want to try it out, go ahead and give it a try.

eh those blatant claims are from sierra glow themselves lor....

and you talk as if I abused my car. you also assumed that I do not know anything about detailing.

i didnt say I do not want to listen or understand. I only said I do not need a solution from Mr.Choong which means if he offers to redo my car, I have to think twice. No point spending my whole day there if after a year, this happens again.

understand?
