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.

Sadly the melting dash has no cure. Once it starts, nothing will reverse/stop the process. I had the same experience, freshly applied 303 won’t stop the dash from melting in warm and sunny days. The worst thing is the glare/reflection showing on the windshield (due to dash being shiny) actually blocking the driver’s vision.

Lol if driving in sunny+warm days, make sure the AC is on and must park in a shade.

It hurts my brain everytime I think about it.

These sticky dashes... are they random across model years, or seen more with earlier 370zs?

No idea, but my personal experience is with one a 09, and 2 x 2010 dashes. My research on this topic on other platforms seem to also point to the earlier 2000 periods also. But I can’t make any guarantee. Whatever the year, take extra caution if your car is a garage queen.

I must stress again, UV and heat aren’t the only thing that cause this. The extreme opposite can also lead to melting dash. Melting buttons happen on garage queen Ferrari’s and Porsche’s as well.

I currently have an 09 Z, 10 G, 11 FX (all the same platform). FX gets parked outside, takes a beating everyday, and no issue. Z becomes a garage queen 3 years ago, G gets driven a whole lot less in this same period (semi garage queen), both dashes started melting during their hibernations. All 3 cars have Covercraft screens, and parked in shades whenever possible.

I am also curious if this sticky dash issues impact all Z's.....

I imagine the materials and processes are the same for all dash regardless of where they were produced. Unless some factories screwed up.

Again, I don't mind cleaning and applying the protectant as long as the dash doesn't crack....
