Kool Seal?
'71 Overlander 27 footer. I've ordered some Sikaflex for various re-caulking, but I notice that most of the roof penetrations carry an old coat of Kool Seal type brush-on sealant. Is this appropriate? Thanks.

Aluminum Kool Seal is a good product that seals very well to aluminum. It is what Avion always used, and is what Dr. G (Donald Gradeless, the Inland Andy of Avions) still recommends. It's getting hard to find, though. I'm not sure if they're still in business. Lowes and Home Depot no longer carry it. Ace Hardware supposedly does, but I've not seen it in there either.

Looks like Panther Rv carries it.

Kool Seal Coating

Airstream always recommended Vulkem. And I see that there are cross references from Sikaflex to Vulkem products, so you're probably fine with those.

Last sealing I did was for my new roof vents, and I used a product from Dicor (Panther also carries them...I'm not an ad man for them, they just had the best prices on the vents and I got the sealer with the vents) that was made for aluminum and so far it's worked very well too.

Best of luck,

Thanks Jim:

I have some silver stuff that was used to refinish an old galvanized steel roof on the shop. I'll have to see if I can still read the label to find out if it's compatible with aluminum. Appreciate the Panther RV link.

By the way, this trailer will likely make its final move, only about 300 yards, in a few months, and eventually be under a framed roof, so perfect on-road durability isn't of great concern.
