Apparently, in my part of Canada, Glyptal is not available due to to some regulation, meaning we are not smart enough to handle this product. Nanny statism strikes again!
But an equal product, probably just as dangerous can be had. It's called MG-4228. I brushed a small amount of this onto the affected area that was porous. After about 10 hours of use, it still hasn't leaked, so all good now!
