Having recently seen excellent performance from the Menzerna 5" pads earlier in the week both on the PC and rotary, I decided to trial the 5" white cutting pad up against a 4" cutting pad when using Menzerna Power Gloss to remove severe defects.

Now, previously, a 4" cutting pad has been the best way to go for applying Power Gloss by PC I have found, as it seems to break down the products most effectively and generate the best cut. But I had not tried a pad as agresive as the white Menzerna 5" by PC, so two big questions I wanted to answer:

> Does the Menzerna pad give increased defect removal power?
> Which pad, 4 or 5", leaves the worst micromarring?

You know the score by now with me... out with a scrap panel!! : :


4" Sonus SFX-1 Cutting Pad
First up, the traditional way of applying Menzerna Power Gloss by PC: a 4" spot cutting pad:



The panel (Peugeot Agean Blue) was swirled up with some steel wool, put my back into it this time as I wnated deeper marks as well to challenge the Power Gloss:



So, Power Gloss by PC I always apply using a slow-cut technique. Spread on speed 3 with one fast pass, and then 5 passes at speed 3 with no pressure at all, just the weight of the PC. Switch off and spritz pad with water. Now, speed 5 for five passes with no pressure. Spritz pad, and then another five passes at speed 5 with no pressure. Then spritz pad and finish off with three passes at speed 6 with medium to firm pressure. Wipe off residue, and the results:











I took many pictures with a few different light styles to try and highlight the finish as best as possible as the effects of micromarring are subtle and hard to photograph. Above, we can see that some of the deeper marks remained, which has come to be expected from severe swilrs when working by PC. Another hit here woud reduce these marks still further. If you study the pictures closely, you can also make out micromarring very faintly - small circular scratches, and many of them very close together. This again has come to be expected when using harsh compounds with a PC - easily removed using a lighter abrasive such as Intensive Polish.
