Another Sticky Dash Issue

nis350

my car is always garage in socal where the temperature is quite mild.

Based on all my readings here, I have tried cleaning the dash with just water with a little soap. the dash would look quite nice and non-sticky, but after a month or so, the dash would turn a bit grayish on the surface, it almost felt like a film because it would turn a bit darker if I just wipe it with my hand.

I would clean it again with water and put a very light coat of meguiar natural vinyl protectant. The dash color would restore and looks really nice. However, after I drive the car under the sun for awhile, the surface started to turn oily and develop glare on the windshield, probably due to the heat.

I have recently repeated the process, but with the 303 vinyl protectant as you suggested. The temperature has been quite cold recently, so the dash still looks pretty good.

I am ok to repeat this process once a month as long as the dash doesn't crack.
