My first DA - speed settings

[oldmaninsaline]

I just took delivery of my first DA random polisher and am wondering about speeds. I've been using a single speed polisher.

My car is a 1992 Dodge Stealth, emerald green pearl clearcoated at the factory. Minor swirls that the polisher using M0216 M2 didn't impress me. So I switched to the ultimate compound which does the job by hand for some larger fine scratches. I go out of my way to be less aggressive with any correction I do.

I use Meguiar's Ultimate Compound for swirl removal and M2116 for color depth and g200416 hybrid ceramic for a final coat. I get astounding results by combining the 2116 and ceramic on the same pad.

My question is what RPM/speed setting should I use for the ultimate compound? The figure I found is speed 4-5 and 4,000 rpm. I'll be using a polishing pad rather than a cutting pad.

There are many variables in agrgessiveness..
The best places to start are with test spots, from least aggressive to more aggressive,
Variables include tool, tool speed, orbit size, pad material, pad size, amount of arm pressure, rate of motion of the arm and the product.
The largest variable is the response of the paint itself.
