Again, thanks! | | | | Joined: Jan 2014 Posts: 3,690 'Bolter | | 'Bolter Joined: Jan 2014 Posts: 3,690 | When I tried to order a bottle, system tries to sub part# 80019…aviation sealer. The one parts guy says it looks discontinued. The other place can supposedly get me a bottle, but only one bottle.
If this is true, and Super 300 is no more….is the Aviation stuff a reasonable facsimile? Been a long time since I’ve used it. Seems like I recall it pretty similar color and smell but a bit thinner in viscosity. That sound about right?

Mr Google says that it has not been officially discontinued.
I called Permatex but had to leave a message. 877-376-2839
I'll report back when they contact me.

He confirmed that Super 300 Form-A-Gasket has been discontinued. The "better equivalent" (his words) is Permatex Aviation Form-A-Gasket Sealant Liquid part # 80017 or 80019.
The difference between those two part numbers is the size of the container.

I know when I used it on my fuel pump fittings, it ran a little. Looks OK now. I did pick up a bottle of Super 300 from my local Advance Auto/Carquest today (only one bottle left), but haven't opened it up yet. Not sure where in Missouri you live, but maybe check out their website to see if your local store has one in stock or click on the "In Stock Nearby" link to see the closest store that might have a bottle.

Permatex has always made top quality products. I've never had a complaint about any of the ones I've used.
