Hello,
I am a complete novice to auto detail and hope to get some advise from more experienced people on this forum. My wife drives a black Mercedes GL450 that has tons of swirl marks and general paint scratches, most of which are not very deep. I am using her car as my first training project to learn how to detail using DA polisher. I fully realize that Mercedes' clear coat is super hard and may present a challenge to even an experienced detailer, not to mention a roukie like myself. Unfortunately, the is the only car I can practice my skills on right now.
I took Meguiar's Detailing 101 class a couple of weeks ago and got inspired by Mike's hands on presentation of the new MT300. I received my MT300 yesterday and spent most of the day today working on the wife's car. I washed the car using the two bucket method and clayed it with blue (mild) Meguiar's auto clay.
Along with MT300 I am using 5-inch backing plate and 5 inch cutting (burgundy) disk to apply Ultimate Compound. Once I go over with the cutting disk I finish the process with Black Wax (G6207) in combination with dark gray 5-in polishing disk. Throghout the day I played with speed settings on the MT300 going from 4800 to 5800 and found that I needed to keep speed around 6000+ to make any dent in the clear coat.
A couple of questions to the folks familiar with DA polishers:
1. I takes me about 45 minutes to cut one panel using Ultimate Compound running at 6000+ speed. Even after 45 minutes I can still see some scratches in clear coat. About 95% of swirl marks are gone but there may be some deeper scratches that can still be visible under florescent light source. I am very careful not to burn through the paint as constantly feel the temperature of the surface with my hand since I am running DA at a pretty high speed. Is this normal to still see scratches after 45 minutes of working with UC?
2. How often do I need to refresh the disk with UC? Is it necessary to keep the cutting disk constantly 'moist' with the polishing chemical? Mine gets dry pretty fast probably due to high speed and higher temperature.
Any feedback would be greatly appreciated.
Thank you,
Alex
