Just a quick FYI to share. Based on commentary from this thread and information gleaned from some car detailing forums, I went ahead and purchased a liter of CarPro PERL (cost $23.99 with free shipping via Amazon Prime). It seems to offer the most flexibility in terms of usage for all the various non-painted surfaces of our Ridgelines. I also went to the Dollar Store and bought a few small spray bottles of their generic auto protectant (I wanted the bottles, I poured the product into an old Windex spray bottle and I'll be using that stuff when I get around to detailing an older car we're selling). I made 3 dilutions, using distilled water, 1:1 for tires, 1:3 for exterior plastics/underhood and 1:5 for interior surfaces. The stuff leaves a great matte sheen and with the exception of tires, a little goes a long way. I'll probably opt for a cheaper product to use on tires, though with two thin coats, it leaves the tires looking great...not too glossy. It's not greasy at all and doesn't seem to attract dust. I'm hesitant to use it (or anything) on the headlights to prevent fading, so I'm conducting an experiment by treating a piece of plexiglass and leaving it outside in an area that sees max sunlight...we'll see how it looks in a year. I also bought some Simple Green to use as a generic cleaner ($9.99 at Lowes for a gallon + a spray bottle bundle pack) based on a conversation with my neighbor who is pretty picky about car maintenance. My cars sit outside 24/7, so I want to get a jump on maintaining the Ridgeline in top condition for the years ahead.
