Just simply try to clean it so there is no residue left. Maybe years of adding product has made the finish not all that great. You could try APC wipe down or Alcohol (do a test area).
Try to get it as perfect as you can and go with something like Meg's Ultimate Protectant. Definitly has shine and this shiz does not dull. I actually used too much and now I have the dreaded glare on the windshield.
I am sure there is other stuff out there, try google.
Depends on the armor all product you use. The protectant stuff works good to protect it from cracking from extreme cold temperatures. The armor all detailing spray though works really well on making it shine. I never got the glare from the windshield though. I've never used the meg stuff on interior. Just maintain it weekly your dash will never crack and always have a nice shine. That's what I do.
The best product I've used so far is 303 Aerospace detail. I've also used Turtle Wax 2001 Super Protectant, but you will definitely get a lot of shine. Both of these products will not "haze" onto your glass and provide excellent protection of vinyl surfaces.
