Default dynomat and paintless dent repair

Does having dynomat on the inside of your door panels make a diffrence for a dent repair guy?

Yes, if there is dynomat or a similar material stuck to the inner side of the panel, PDR on that panel will not be possible unless the material is removed.
You can ask your local dent guy if there are any other options but I don't think so.

You have dynamat on the metal of your door? If it's on the plastic, it's not an issue.

They take out dents by pushing the metal back into place with relatively sharp metal tools from the inside, so you could see why it would to be removed.

You're supposed to apply matting matierals to the metal of the door...

Basically, every part of the door that resonates at an audible frequency (most of the door assembly).

It works by adding weight to the door's structure, the weight lowers the frequency the door resonates at. If you add enough weight to the door, the resonant frequency drops below an audible frequency, and rattles/etc go away. Sound quality increases, as the door no longer absorbs any of the speaker's energy/movement.

I understand your point, but on my car, the plastic makes more noise than the metal, because it vibrates and buzzes from engine vibration. If I were to do some noise reduction (which I think I will this summer), I'd start with the plastic. I might be an odd case though.

Secondly, this might be a stupid question, but isn't there a large part of the outer metal that is largely inaccessible without completely gutting the door (not just taking the plastic pieces off)? That's why I asked, because it would depend on where the dent was.

nope, you just have to work through the access holes that are there. It isn't fun, and you WILL bleed a fair amount in the process, but you can cover most of the outer surface of the door this way.

Do you have to rip off the plastic covering (looks like thick saran wrap or something to keep out water), and reglue it if you do this?

Ah, gotcha. Thanks for answering my inane questions. Those pops a dent things seem to work for shallow dents. Creases, or anything where the paint has been damaged are beyond help. DON'T use it on anything but original paint, it'll rip the paint right off.

for removing matting, especially if it's in small pieces, you can grab some canned air, invert the can, and freeze the area in question.

You may want to cut out the square in advance, if it's a large sheet in the way, and freeze it from both sides.

Then simply hit the frozen spot from the outside of your car and it should pop the piece right out. Failing that, you should be able to pry it out with a screwdriver from the inside.

If I cant cut it out, I'll try and freeze it. Good idea.

Yeah, even if it doesn't pop right out while frozen, it should be 10x less sticky and shouldn't be too hard to pull out with a flat-head screwdriver.

Just wear a laytex glove or something to give you an extra layer so that you don't freeze yourself to it...
