Proper preparation of the dash surface is critical to ensure a permanent bond. This includes proper cleaning of the surfaces from any contaminants that may react to the adhesive and the proper use of primer (a.k.a. adhesive promoter) before installing your dash trim.
It has been found that even the pro installers from time to time either skip a step or improperly clean and primer the dash before installing the trim, only to find later on that the bond has weakened and the trim has lifted up or peeled away. Proper preparation is not at all difficult, it just requires a few minutes of time.

Cleaning: It is important to make sure that the dash surface is clean, but also free from contaminants, such as Armor All® or other petroleum based products. Use a good de-greaser or solvent to ensure a clean surface. You can test a spot by using a piece of masking tape on the cleaned surface. If the tape does not stick well, it needs more cleaning (remember to re-clean the area you tested to make sure there is no residue left behind). Be sure to use clean, lint free cloths. Turn frequently to ensure use of clean areas of the cloth. We like to use a follow up step with rubbing alcohol and a clean cloth for good measure. Then we use a lint free cloth dampened with water and buff with a dry cloth to get ready for the primer.

Primer: It is important to note that priming the dash surface does not replace cleaning it. Many of today's dashboards are made of plastics that are very slippery. Use of 3M Adhesive Promoter chemically modifies the dash surface and promotes a good bond with the 3M foam adhesive. When priming, apply one even coat and avoid building layers of primer, which can compromise the bond.
Here is an excerpt from Tips from 3M Tech Service, by Dale Stewart, 3M Technical Service Specialist, 3M Automotive Division, Vol. 1 No. 13:

"It is important to be aware that priming the surface will never take the place of cleaning it. It is crucial to do both. Prior to priming, be certain to remove oily residue from dash surfaces by using an appropriate cleaner such as 3MTM General Purpose Adhesive Cleaner or 3MTM Prep Solvent 70 and a clean, lint free cloth... the average dash kit takes approximately 40-60 minutes to install if all surface protection steps are correctly observed. Cleaning takes about 10 minutes and priming about 15 minutes depending on the size and complexity of the kit. However, reinstallation time for a failed application can take anywhere from 60-90+ minutes depending on the size and location of the failed part...It is time consuming to remove wood trim and clean and prime the interior dash surfaces for re-installation. 3M encourages installers to plan ahead and invest their time in the initial preparation for best long-term results."
