I saw these items * ace hardware kanina..Di pa ko bumibili, I just would like to have some opinions regarding these items..

Auto Gard Rain Repellant = P100
Auto Gard Scratch Remover = P125
3M Scratch Remover = P270
Turtle Wax Scratch and Swirl Remover, forgot the price.

1. Anybody already tried these?
2. How effective are these items?
3. Does it (scratch/swirl remover) damage the paint?
4. Does the AutoGard Rain Repellant cause judders on the wipers?
and another thing..

How can I effectively use Turtle Car Wax? Bumili kasi dad ko.. Though alam naman nya kung paano gamitin yun, paano ang tamang way ng paggamit nito (as experts or sanay na in waxing)? Could you share some secrets kung maaari? hehehe

replies will be greatly appreciated
