A few months ago I applied sticky dash fix to my upper dash and doors. I'm happy with the results. Since applying it I haven't had the slightest hint of sticky , today it was 110f. The stuff is time consuming to apply. It took me over an hour to do 1 coat. If you don't like to paint consider having someone else apply it.

 

Good for you. It does help. How many layers you apply? I think i did around 4.

 

I did one coat.

 

It's great that you're happy with the product and results. I'm sure more new posts will come up, looking for a solution to the sticky issue.
