I took your word on the rustolem color and went ahead and painted my voltex bumper lol, so far looks pretty good got a little bit of trash in the paint but going to sand it down and polish it up but here's a picture. Still need to install it and see how close it matches my paint.
Dang dude this looks great!
Gonna go buy some stock in Rustoleum Sunrise Red. Hashtag NewFormulaRustoleum
Yeah the new 5 nozzle cans are nice too, I set it to nozzle 4 for vertical spray and it has good coverage too, one can and did two coats is what looked best for my test panel.
Nothing personal is just my humble feedback. For a job on the cheap, looks great, but for someone that has an eye for paint... Is not great. Normally any bad paint job looks good on pictures, but here I can see the "orange peel" effect even from 3 feet away. Not saying this doesen't work, but for anyone that is thinking of attempting this, just bear in mind that spraying paint like that almost never result in a great job. Good effort anyway
bumping this up as a thank you to B-serious - buying some of this rustoleum sunrise red.
Stupidly put dynmat inside my car - did very little to reduce NVH, but sure a F--- made the car heavier. I instead, got a 5 lbs sound curtain and used it to fill the space where the rear tray used to be and that did wonders to reduce all of the echoing.
Back to the dynamat - don't ever do it. Went and did the dry ice bit yesterday. worked decently well to remove stuff, but also removed paint and a lot of the OEM sound deadening material in the process. Now have bare exposed metal in these areas.

Anyway, got some cans on order to un-fu** my interior.
Man, this is EXACTLY what I needed to see. I have to repair some cracks in my OEM lip. That I can do super easy at work with some fiberglass patches and such. I was contemplating having it painted professionally but Berlina Black is very, very close to Rustoleum black. I was tossing around the idea of doing it myself and this just pushed me over the edge. I'll probably end up doing it at work since we have a ton of room two hangars.
I'll probably end up going super heavy on the 2K also just to make sure it lasts.
As far as the dynamat is concerned, you don't have to completely coat every inch to gain benefit. I used 3M Thinsulate (automotive material for Acura/Honda vehicles) which is very light and hydrophobic. Does a great job.
You are correct about the Dynamat adding weight. Would not use it on a track car but for a lot of road trips, it is nice.

haha yep!
Unsurprisingly, dynamat does not quiet down booming or droning noises.
The most simple way to think of it is to think of a popular use of dynamat in the car audio market. Tpically, in audio installs, it is used to amplify booming noises. Drone is similar to what a subwoofer does.
I have only dooe a small amount of audio engineering in my past career, to meet an EU noise emission standard.
You would want a sound blocker/reflector on one side and a sound absorber or diffuser on top of it. That would cut down on cabin noise.
Dynamat will just make the booming sound more solid and punchy.
Proper use of dynamat is apply 25% coverage. Divide each flat panel area into imaginary squares. Add a piece 25% in center of that square. So a patchwork of square patches of mat here and there.
Adds mass to change resonant frequency. Use only on flat panels that can easily vibe. Door panels perfect example.
Thought experiment. Imagine a bell, like at hotel desk. How much dynamat would it take to make it not ding? Only a small bit would make huge difference. While adding a ton barely makes it better.
So it prevents road noise from turning panel into a crude speaker. Repeating the road noise into cabin.
But now you also need something to block sound passing through panel. Something full coverage, like the automotive thinsulate example. Fibers are cut to exact length to kill typical car sound frequencies. So its not just ski jacket thinsulate.
