If you fully break down the polish why would not using a rotary cause the polish have durable fillers? Results may be different but I don't see how the chemical makeup would change.
Any links to support this? genuinely interested
Very strange, Ive used the exact same steamer on my girlfriends 2002 Grand Cherokee a few times and never experienced any issues. Glad you got it cleaned up.
I find perl to be a fabulous overall product (love it on tires). However, in my experience trim isn't the best surface for it. I've found that it runs off trim in the rain leaving an oily residue on the paint.
For some reason it doesn't come up very often. I noticed the issue after doing an ONR QD wipe down. Googled it to see if anyone else had experienced this, and found out that its a pretty well documented issue...
