dnobel Posted August 29, 2012 Share Posted August 29, 2012 I recently performed a paint correction on the roof and trunk lid of a classic Prius using Hyper Compound and a pair of Optimum MF cutting pads. The pads were cleaned and rotated after completing each section. After the final cleaning up, I noticed that both of them are exhibiting signs of severe compression or failure of the center 3" of the foam core, so that they are now visibly concave. The pads were brand new and installed on my GG6 DA; they were never run with the machine over 5. I cleaned them between sections using Mike Phillip's terry towel technique followed by the nylon pad cleaning brush, both with the machine set at 2. At the end of the job, I washed them under running water after spraying with Pinnacle XMT pad cleaner, then let them air dry on a Grit Guard. Any idea what might have happened to them? My suspicion is that this is related to the cleaning process between sections, but I don't think I did anything improper or unusual. Link to comment Share on other sites More sharing options...
Perfections Detail Posted August 29, 2012 Share Posted August 29, 2012 Is the griots brand new? Or have you been using it for a while? I've notice that brand new griots create a ton of heat until they break in. Link to comment Share on other sites More sharing options...
twstd1 Posted August 29, 2012 Share Posted August 29, 2012 I would like to add pressure issue to the list of possible culprits. Also, I've found that with MF pads, less section passes are needed for correction, as opposed to foam. Furthermore, I rarely (actually, never) use cutting pads as OPT's finishing pads are sufficient for correction in every test spot that I've done. Even on hard CC.

Joel Blake Posted August 29, 2012 Share Posted August 29, 2012 The GG units are one of a number of rebrands across the globe. All have a reputation of heat transfer and melting pads. Link to comment Share on other sites More sharing options...
dnobel Posted September 1, 2012 Author Share Posted September 1, 2012 Thanks for all the replies! Speed 5 may exceed our 5000 OPM recommendation, the GG6 transfers a ton of heat, and we're you using our backing plate? Chris, you would be correct, as the GG6 set at 5 is apparently 6000 OPM. Where is your 5000 OPM spec published? I definitely missed that. And I have been using the LC backing plate, not yours. The only Opti-Flex I saw available on AG was the 7", obviously too big.
