ive got an 02 wrx with 53,000 some miles on it .. since about 15,000 miles ive been using s100 wax, and i wax it every 5 months on average. i just washed/waxed it yesterday and i notice that, while it looks good, it doesn't have the same shine it used to. what would be the best product (or combination of products) to use to bring back that look? ive claybared the car once (about six months ago) and basically only hand wash it and hand wax it. but i havne't really used any polished or anything like that. and the color is silver. if that's important.
