Don't think either of the problems are water spots or wax. I used Meg's #2 on the interior trim (by hand) with no effect. I've had the same type of spotty dulling/discoloration on exterior trim on other cars. Back to Black just doesn't get rid of it. Someone once told me that it was some sort of bacteria. Don't know if they were right, but it does have that type of amoeba-like shape to it.
Looking at the interior trim again, it almost looks like sun damage (PO lived in FL - serious water spots on hood and trunk that only a PC with Meg's #83 could cure). You might suspect that the trim was affected by a chemical, except that the effect is uneven, and the same part is this discolored whitish mottled effect on both sides of the car. Of course, the PO might have also tried some sort of harsh chemical, in a sloppy uneven manner, on both sides, as well. There has been plenty of evidence that the PO didn't take very good care of the poor beastie.
PO examples: 2001 Miata SE. There are structural "pockets" behind the front wheel liners, immediately forward of the lower door hinges. I had heard this was an issue, so I pulled each front wheel and the back portion of the liner, and extracted a double handful of decaying leaves from each side. Rain that comes down the back of the convertible top is directed to pockets that are actually inside the car, and thence to a pair of 1" diameter drain pipes that exit just forward of the rear wheels. The PO hadn't bothered to clean them out, leaving me with a soggy rear package shelf. 10 minutes of work per year is all it takes to prevent the problem. A number of stone chips in the front. Working those as time permits.
Going to the PB site, the Trim Restorer is advertized as a protective dressing. Does it also include vinylizers? All of the products I've seen like this in the past have been intended primarily for soft vinyl, not hard plastic. Am I to understand that the PB product works on both?
