Maybe it's for applying to asphalt as opposed to containing asphalt, then?

Those look pretty nice. What did you paint them with......... or maybe you can point me to the previous thread?

Thank you for the compliment, AB.

I painted the horns after scraping and sanding them to a smooth base condition. I applied an ACRYLIC etch-primer(spray can), spot filled, sanded and re- primed a few casting flaws and then applied the ACRYLIC finish coats{spray can}.

I wished to have that black finish similar to the original Altec finish and very similar to that of black auto GT stripes and auto side window surround trim. This was readily available as a pro paint in a spray can - at a price.

The price was a problem because I intended to use the same paint for the cabs, also. In hindsight not a good idea due to limited applicaton fan width.

I found a DIY(cheaper) auto acrylic in spray cans with the right lustre and used that. It worked out fine on the horns.

Lustre: Not MATT, not SATIN. In between but closer to matt. An auto paint store will know what it is. Go for the better product if you are only using it for horns or small pieces.

Regards, Marshall.

At least in its 60's - '80s formulation, the Charcoal Black was a perfect match.

I'll have to give this some thought. I may go non-stock on the color. Every time I browse the spray paint at whatever store I happen to be in, I see satin colors that I'd love to try on something.

This is the asphalt paint I used to deaden the back of the 828 bass cabinet horn flares.

I got the 1 gallon size. It's thick, black and easy to use. I mixed a lot of sand in with it. But it's not nearly as thick as the solvent based tars I've used. But water clean up and low smell. You need a few coats.
Don't know how practical it would be on a surface that is handled or touched a lot, like a 511 horn.

Hey Pano, What is your take on it, as to performance ? Works Great huh ? And this brand is Solvent-Free.

Interesting, I had no idea an aspahalt coating was possible without an organic solvent.

Well it's easy to work with, being water based and all. But it's just a very thick paint, not a paste like tar. So I'm not crazy about it. Takes too many coats for a good, thick layer.
You WILL get it on you, so wear junk clothes. I also wore disposable gloves.

Darn it....... that Vapco went for $25 plus a 10% buyers fee and 6% sales tax for two gallons..... 2 lots of 2 gallons each. I guess I can use paint. I can pick up a gallon of latex a lot cheaper from the Habitat for Humanity ReStore. I may have some out in the garage, but that is really old and may already be half dried.
