Just finished the splatter painting of the trunk - used the GM product from Ames - looks great. Now I'm wondering whether is makes sense to apply some sound dampening material (e.g., Dynamat Extreme)? Looking for thoughts as to whether it will diminish value of car, lead to moisture capture / rusting beneath, will serve intended purpose, etc.? Thanks!

I stuck a couple sheets under my gas tank. The trunk floor is like a big drum.

I am so disappointed with splatter paint, not sure if I will ever do it again. I've gone through great lengths to strip, prep, POR-15, scuff, and shoot the splatter, as well as clear it, and it always comes through. The slightest bit of water and it's trapped under the mat and it leave rusty residue, regardless of what I've done. I just don't get it or something. Think maybe it's from around the drain plugs?

Not to mention the aerosol cans of splatter aren't cheap, and they don't cover jack for area. I think the clone took like 16 cans? More I think. Then it was like 10-12 cans of clear, and it still came through. I went back over it and used clear satin engine paint and it's holding up way better, but still have ghosts etc of where water got under the mat. And I'm not talking about a lot of water. Think the one time I left the trunk open in the rain while I unloaded groceries, maybe 5 mins.

Next time I'm going to use truck bed liner and be done with it.

If you put sound deadener on top of the splatter, it will lift the splatter paint right off the floor. That I'm pretty sure of.

For the sound deadener I would drop the tank and spray lizard skin deadener on the bottom of the trunk floor. That way you have a coating and not a glue on matt that moisture can get in between and rot the floor out.

The problem is people use the splatter paint in the cans and it is complete junk. The proper way to do splatter paint is pretty involved but gives you killer results. Invest in a pressure pot gun and a product called Zolatone. It comes in quart containers and different splatter colors. It is very durable and doesn't get damaged with water like the rattle can junk. It is latex suspended in a tranparrent paint. You don't shake it, you stir it to mix.

If you put a mat down over your splatter paint of course it will hold moisture under it , it's a rubber mat & won't breath. If you use a cloth type mat you won't have the moisture under it because it can't wick the moisture from under it. The best is to use no mat at all in your trunk & let the splatter show & you won't have to worry about moisture under those rubber mats.

True the professional spray on stuff via the proper gun etc is the way to go, but then you're talking about an even higher cost. How much would that cost? And I was only saying because the poster already has invested in the rattle can coating.

True too on the mat, but with no mat, stuff slides around and can damage quarters. Groceries? They would be all over the trunk by the time you got home, and the mats help deaden sound also.

In the clone I used the accessory mat on top of the regular mat, it's thick, and nothing slides around. It looks great too. The LeMans from the factory used a felt mat, and I chose to go to the previous years thick rubber mat. I will do the same this time around, and add the thick rubber accessory mat on top of that, just like the Olds. PY sells it, and it has the Pontiac logo on it.

I also bought one of those round, canvas jumper cable bags, and tossed it on one side in the drop off area. Bought a small canvas tool bag from Sears, put my road repair tools and stuff in it, tossed it on the other side. Looks great, contained, practical, and out of the way.

On the underside, sure, you can spray lizard skin on it, but I just used the bed liner stuff, comes in aerosol cans and is easy to apply and touch up. It dries harder and last longer, and does add some sound deadening. I put a sheet of dynamat on top of the tank, which helps with tank and trunk drone, squeaks, etc. It works.

Timely topic for me as i just installed a trunk pan... PO had the trunk area pretty gooped up with all sorts of material. Some sticking good, some not. I just took the wire wheel to it today just to scuff off the loose stuff. Going to shoot some Epoxy primer on the new metal and over the other areas.

AMES rated the Eastwood rattle/splatter paint as being pretty good, so am going to try that and clear. Regardless, it will be 1,000 times better than what I started with!

I have some of the extra thick Fat Matt, and like the idea of using it on top of the gas tank. I was going to use a large chunk of rubber sheet, which I purchased for cutting wheel well mud flaps. Anyone need some custom mud flaps cut?

Reading this thread made me think of this 25 year old can of spray paint I had in my shop. I guess this was what PPG/Ditzler was selling as spatter paint back then.

Both flammable and water soluble which seems kind of strange, but that's what the can says.
