I got an old (probably from the mid 80’s) white Volvo fender from my neighbor to use for playing around with my rotary buffer. I went out into the garage last night and put the fender up on some saw horses and then clayed the fender and then laid down a bead of M105 (new version), put on my Solo burgundy wool pad, primed the pad with some #34 and began to work a small section of the fender. The buffer immediately just grabbed and grabbed, it did not buff smooth at all. I worked it for less than a minute and then tried wiping off the residue with a microfiber. The residue was not coming off, so I sprayed some #34 on it and I could still not remove the residue very well. I had to spray some APC onto the fender in order to remove all of the residue. I don’t know what the deal was. Every time I tried it, I got the same results. So then I switched to a 5.5” Lake Country Hydro-Tech cyan cutting pad and worked the M105 in with that pad. It worked a bit smoother but it was still gummy. I kept working it until it was almost gone though and that time I was able to wipe off the majority of the residue, but there were still spots that I could not remove all of it, so I had to use the APC again.
Last week I used the M105 and the Solo Burgundy wool pad on the plastic hood of my John Deere riding mower after I lightly wet sanded some heavy scratches out of it with 2000 grit sandpaper and I did not have any problems like this with the M105 at all. In fact it worked great. I know that was plastic and this is paint, but I was still surprised how much trouble that painted fender gave me.
Here is a 50/50 of the mower hood. The right side is untouched and the left side is after 2000 wet sandpaper and M105 with Burgundy Wool and then M205 with Polishing pad
Can any of the pros out there give me some tips on what I should try with that fender I am playing with the Rotary on?
