I need some advice on sticking DynoMat to a painted surface

[ChickenRammit]

I am going stick some dynomat to the inside of my firewall.

I just finished cleaning and priming the area i want to stick the dyno mat to.

Will the dynomat adhere pretty well to the primered surface, or should i throw on a coat of gloss for a smoother surface?

Or if anybody has any other bright ideas, i would like to hear them.

Dynamat isn't that fussy. As long as the surface is clean and grease-free it should stick fine. There is a small wooden roller that is typically used to really crush the stuff down and into all the little voids.

I've acutally used a heat gun to warm the stuff up a little so that it follows the contours more easily during the initial installation.

I have some dynamat extreme. I pulled my interior to access the cancer situation. Went wheeling and the floor was just too hot with bare metal. All i did was vaccum the floor real well and started attaching it to the tunnel area. It stuck very well and hasn't lifted any.

Chicken, I have a bright idea. You could dynomat my firewall too while your at it

I used the dynomat extreme on one of my doors and the inside of the roof. I wiped the panels down with alcohol and stuck the stuff on over the original paint/overspray. You have a great question regarding it sticking to flat primer, unfortunately I haven't tried it and can't comment on that part. I used the little roller to smooth it out. It is stuck on there very well. Now I just have to do the firewall, floor, rear of cab, and other door

Is that your only classic chevy? I got my pickup going but the engine in my K5 took a dump. I'm glad I have at least one running.

I was under the impression primer absorbed moisture.

so mix that with dynomat and you have a rust party.... ask my floors all about it, po had dynomat on it

lacquer primer absorbs moisture...

it will stick fine to primer, but as in any situation, a paint coat will complete a coating system and seal the metal up better..

it's like bedliner.... sure you can just herc over primer, but paint makes it that much more durable...
