This is not for stopping the corrosion
but possibly something similar is available for repairing aluminum
The product in my photos is about 20 years old and was manufactured by MMP ( Modern Maintenance
Products) International Limited in North Yorkshire, England
MMP was acquired by a US company Devcon Plexus (now ITW Plexus) in 1999 and I could not find this product on their website.
But possibly something similar can be found at a well equipped hardware
store? This one "contains epoxy
resin and a blend of polymercaptan and polyamine hardeners".
Perhaps something similar is available at a well equipped hardware
for thought? Let the experts chime in..
