The coating is black someone else told me about that too.That the OKC plant used Automotive Undercoating to dampen their 511E's.I'm pretty sure it was Phil Brennen eBay Moniker (aaokc)

Maybe? Horsefeathers and applesauce. Certainly nothing to base your previous "statement of fact" upon;

So you can go to your local auto parts store, pickup a couple of cans and spray it on,just mask off areas (Masking Tape) you don't want to cover.

That's an awful idea. A lot of that stuff never really drys and is gummy. It may outgas for a long time, too. I got my 511B's on ebay cheaper than normal becasue they had that crap sprayed all over them.

Never really dries (hardens) is good. Gummy is not.

There is a differance between drying and hardening. Silicone glue dries* but it doesn't harden. A lot of the undercoating in spray cans is just nasty for use on horns........ it doesn't even do a good job on cars.

* I suppose it could be a chemical reaction, but most people talk about stuff like glue and paint drying no matter if it's a chemical set or evaporation.

Wasn't that wheel well stuff used on the sheet metal horns called Aquaplas?

Anyway, you can do the damping on the cast horns with a bag of moistened sand sitting in the top lip or water if you're not worried about a few drops splashing around but my favourite is to use wax and some wicks - the original night light show - how *ing romantic is that? You'll get extra kisses and she might even tell her friends that your hobby's OK.

Aquaplas is not even close to being what most often gets used as rust-proofing or undercoatong on cars.

Yes I was referring to the stuff on the big horns. I believe it is Aquaplas. I didn't think anything else was used on them, be it wheel well stuff or truck bed liner, I thought they had misinterpreted the product.
