llebcire (Eric):
I think wannafbody is correct: the damage that you`ve posted a picture of is from "improper" cleaning, most likely a) chlorine-bleach-based product (think Clorox wipes) I really have no proof.
I have seen "similar" problems in Ford and GM plastics and vinyls, BUT I always thought it was a flaw in the production of the plastic or vinyl, IE, the plastic resin was not well-mixed during the injection molding process and was missed in Quality Control, both by the part manufacturer and the assembly line inspectors, AND the dealership customer delivery prep personnel. When I use a vinyl/plastic protectant on some of these pieces, it seems blotchy or even streaked, like the plastic does not "absorb" the protectant when wiped off. You can clean the area again with an APC, reapply the protectant and wipe it off, and it will STILL be blotchy or streaky as before. Trying to reapply the protectant by itself again and wipe it off yields no better results.
THAT should never happen in a Honda. Their Quality Control at all levels is second-to-none, which leads me to the conclusion of improper cleaner damage.
One of the "problems" with vinyl protectants is that some are glossy and some are more matte, natural, or low-gloss in appearance. I dislike the high-gloss look as the reflection off the dash can impede a driver`s vision in certain sunlight angles during the day and be a safety hazard. Some like it though, because it imparts a freshly detailed appearance. it also "covers" those blotchy or streaky plastic imperfections until the protectant burns/gasses off in the hot temps of a summer sun inside the green-house windowed vehicle interior.
I would NOT recommend rubbing alcohol (70% iso-propyl alcohol, or IPA as it is abbreviated here in this forum) as a cleaning agent on vinyl. Hard plastic, maybe, but not soft INTERIOR vinyl. (I say interior as IPA is used as a cleaner on EXTERIOR vinyl, like door guard side molding). There is also a great debate about using citrus-based Limonene cleaners and whether they dry out or "dissolves" the organic (carbon-based) solvents in plastics and vinyls. I think diluted and wiped off in a timely fashion, they are safe, but used full-strength and left to dwell for a length of time, then yes, they cause problems.
I still prefer AeroSpace 303 protectant, but that is me, because it is more "matte"/natural in sheen/gloss. Meguiar`s makes some consumer-level protectants in both a low-gloss and high-gloss sheen. You may have to "experiment" with different protectants to see which one gives you the best look at covering/hiding your damage and how frequently you will need to apply it to maintain that look.
