Do you guys think it's worth it to frequently treat my weatherstripping/door seals and black plastic/moulding parts with Mother's Back to Black or an equivalent silicone spray or lube? Soon it will be 115+ degrees here and I know how bad the heat and dryness trash these materials. I'm concerned about keeping the wind noise down and the seals in good shape...just wondering if it's worth it? And if silicone is bad for them?
Any other tips for keeping the car quiet on the highway (short of Dynamat).
