Thanks to the both of you, I have found a Super Clean degreaser available in Canada. This is the website of it; SuperClean - Dissolves Grease. Super Easy. Super Fast.
Does this look like ther right stuff? I had considered using Easy-Off oven cleaner as I have used that on plastic kits but I am unsure what the reation to the pig metal will be.
I love this guy Marty's videos (Marty's Matchbox Makeovers). He strips and repaints one or two a week for his YT channel. He hasn't ever seemed to settle on a perfect stripper, though. No two types of paint strip the same way.
