a) tuff kote system 6
--> there was a promotion the last time, buy tuff kote anti rust
and get system 6 free. I look at the paint work but cannot detect
any difference. Maybe the benefit is only obvious when u have
driven the car a few more years.
b) tuff kote sound cladding
--> no 100% insulation lah. The best insulation comes from the
car manufacturer. Eg. if u test drive one and it is v quiet =>
that is better than hunting around to insulate the sound. if your
car is noisy, check the source of the sound. Sound cladding may not
be able to keep that source out of your ears.
