Dash and ultima interior guard plus issues

Hello,

I am having some issues with Ultima Interior Guard Plus on my dashboard. I love the stuff, however, my dash board has a texture to it, and using the foam applicator and then buffing with a microfiber, I seem to only get the raised portion of the dash coated nicely, where the recessed areas still look dull.

This picture's lighting is bad, but I just put this in to show you the texture.



Any suggestions on application techniques? Or should I looks for a different product to use?

Thanks!

Thanks for the fast response. I forgot to mention, I did give it a good scrub down with 1z einszett cockpit premium. It seems to be the foam applicator, it just only really hits the raised surfaces of the dashboard.....
