Porter-Cable 7424 Polisher

[Perfectlap]

remember to moisten teh pad with quick detailer or water before applying wax or polish.
The 1Z paint polish is very popular with Porsche owners and on the Autopia site.
Use a Sonus white SFX3 pad to remove light swirls. There are more abravise cutting pads for really bad swirling but that doesn't seem like your situaiton.
The key is to move sloooowly at 4 or 5 on the speed dial, generating heat is important to allow the PC to buff out the product without having to remove residue by hand. Let the polisher sit on the paint surface under its own weight no need to push down.
