Undercoating

[Lynn]

What are you guys using for undercoating on the underside of fenderwells and the insides of the quarters?
Someone suggested 3M 08864 rubberized Body Shutz. Still available, and you can even buy the applicator gun for it.

How close to the original? How many quarts to do all four wheel wells and the two quarters? How long after shooting it do you have to wait befor shooting spatter paint in the trunk?

Sorry for all the dumb questions.

Lynn,
That wasn't a dumb question at all. I've also wondered if there was a product out there that would duplicate that thick lumpy sound deadener we find in those areas. Short of slapping on tar with a tongue depressor, I don't know what to do to replicate it.

The Body Schutz is good for leaving an original style heavy, pebble grained finish but those cans sure do not go very far. It could take a dozen cans to get the desired finish just in the wheel wells.

At 21 bucks a can, not looking so good. Suppose anyone sells it by the gallon?

If you have a decent air compressor, you can buy it in quarts from the paint/body shop supply store (I use Finish Masters locally) along with disposable applicators, our local store has a board with the different products actually applied to the board which helps with selection.

If you can take a sample or photo it could help as well.

Plan to upgrade compressors when I get the shop built. For now I have a 5 hp 60 gal oil free. BTW, if noise is an issue for you, don't get an oil free. But at least I don't have to worry about oil getting in my paint. It works fine for painting cars even with hvlp equip. so I am guessing would be adequate for spraying the body shutz.

Steve. I think I am going to get 6 quartz and the applicator.
Look on this page:

The 3M applicator is about $100. I am thinking the Astro brand ($25)and just consider it disposable. Can't imagine how much thinner and acetone I would go through trying to get the applicator clean, but probably close to $25 plus all the time it would take.

Anyone use the 3M in quarts and either of the applicators?

There are a couple other products on the same page that look promising, but I am not up to using my car as a guinea pig on this. The Rusfre brand is only $25 a GALLON. Also Transtar makes a rubberized undercoat available by quart or gallon, priced similar to the 3M, except it is available by the gallon. I have used other transtar products, and always found them acceptable.

The only thing I know for certain is that I do not want an aerosol product. Tried that many years ago and you can't get the really thick texture I want.

I am guessing some of you guys restoring and building high end cars have some experience with shooting the sound deadener. Any info you can share would be appreciated.

Lynn, you can buy rubberized undercoating at auto parts stores for $6 to $7 per can, I've been using it for many years on many cars &amp; trucks, all of the brands I used has the wrinkled look and turns out nice, I've noticed that some dealers piled it on thick, like our local dealer used to do, others barely covered anything .

Actually, I used a can of the black bedliner spray recently and i think that may be the way to go on a budget. It gives a thicker, more grainy layer than regular spraycan undercoating.

I have always used the 3m body schutz and the cheapy gun that goes with it. 1 can per side. If you want to add some body to it for a thicker look, use the clear rocker panel coating that you can get in the supply places first, then top coat after its dried with the 3m. It make a big difference in distance your spraying from along with air pressure. You can also mix a little reducer in to change consistancey and help it go farther.

Thanks Micky.
I am going to order 6 cans; one for each wheel well and one each for the quarters. If I don't use it all, I have an upcoming project I can use it on.

Steve's idea of the bedliner is appealing, but I have gone this far, being pretty darn close to factory correct, that I think I want real undercoating. I appreciate's Mike's response as well, but really want something with a little more body that what I can get out of the spray cans. In fact, I have a couple of spray cans here but just didn't like the way it came out when I tried it before.

Thanks guys.
