Just bought some seam sealer at the auto paint store, its brand is McKanica, it comes in an aerosol type can it is polyurethane based, paintable within one hour, it states excellent adhesion to bare or primed metal, stays flexible and is firm setting. Anybody heard of this stuff or used it.

It being polyurethane based will that cause any problems? I plan on putting it on over spi epoxy.

thanks

here is the best seam sealer that I have ever found,
3M Heavy Drip-Chek Sealer part number. 051135, 08531

I have to tell you Big Don, I have used a lot of "Drip check" sealer in my day, NEVER again. If you started using a 2K sealer, you will never use drip check again either. It is a part of history like lacquer primer.

Aaron, what are you sealing? A spray on sealer is a pretty specialized product. Here is a little "Basics of Basics" on seam sealing....(CLICK HERE)

The stuff we use at the shop is made by Lord and is called Fusor. It's great stuff. You use it with a hand pump type gun. They make all kinds of different adhesives, glues and sealers. here is a link to there sealers page. http://www.lord.com/Home/ProductsSer...2/Default.aspx

I am planning on using it on the hood brace for anti-flutter, I like how it states that it stays flexible and is firm setting. I appreciate everybodys suggestions on what to use, I guess nobodys tried this stuff so I ll just give it a try.

"Anti flutter" is a whole different thing than a seam sealer. I will use a urethane 1K seam sealer on some door reinforcements to skin, but rarely. The "anti flutter" is a foam, and is called "anti flutter". You can get it at the same place you get all seam sealers, like the link short shift has provided.

The wiki Rust article has a section on seam sealers. Includes links to all of the seam sealers mentioned in this thread (and several others), plus a link to Brian's article on Seam Sealers.
