I purchased this package recently for my 1998 Nissan Sani. The colour is Claret Metallic (purple). This vehicle is does not get garaged (my wife's car get's that dubious honour), and is thus exposed to the elements.
I have previously used my rotary polisher to remove swirls and scratches and have clayed the body work.
I was a bit lazy this particualr day (the first time I used this kit), and just applied the polishes by hand. The result was outstanding!! The paint looked like it was glimmering. My wife still commented on the fact that it look like a sheet of water lying on a mirror - and this by hand!!!
I can definately recommend this kit to anyone with a dark colour car - you'll be amazed at the results. This kit is a winner and well worth the price.
