I feel like the microfiber pads allow 105 to retain is moisture more than foam.
What are all your experiences/thoughts?
Like anything, there are all sorts of variables. I assume it depends on the situation.
Then there is they types of foam it's used with.
I mostly use 105 with a large pore light cutting / heavy polishing pad in an effort to keep the liquid cooler as it's worked into/on to the paint. It works well for me so long as I'm not in the sun!
This season I plan on trying it on the closed cell hex logic, and Hydrotech cutting pads, and see how it behaves.
When I was first learning to deal with real hard Corvette paint and failing miserably in the middle of a job, I got in contact with Dana, "Asphalt Rocket" who coached me through the use of M-105 with a rotary polisher.
One of the things he kept bringing up as a common problem was the tipping of the machine, allowing air to get up under the pad between it and the paint, making an already short work cycle even shorter as this tipping would allow the product to dry before being worked long enough to produce the desired results.
I tinkered around with the knowledge he had given me and quickly observed that his guidance had merit.
That whole "product drying prematurely" thing stuck in my mind, which led me to read Kevin Brown's work on the use of supplemental wetting agents, which led me to reading and practicing everything that I could find by Kevin.
Kevin was kind enough to make time to pull the car off to the side of the road and hold a few phone conversations with me on the use of M-105 and wet sanding etc. The guy is brilliant!!
Taking all of what I read on here, got from Dana, got from Kevin and learned through trial and error in the garage, I haven't found a compound to outperform M-105 yet.
I think the retention of moisture is very important when using M-105, and nothing in my experience retains moisture better than the MF pads on an old school DA polisher such as the PC, GG, HF etc. but too much moisture, as in too much product, opens up a whole new set of problematic conditions.
It took a while to get through the learning curve, but now through it I can only hope Meguiar's never discontinues M-105, and that the "Latest and Greatest" drives the price of M-105 down over time.
This is all "just for me" commentary. To each his own.
