 This is an old American lock. I don't know how old it is but it was in pretty tough shape. I got it in a lot from eBay. I'm in a bag kind of like that. You can just imagine what was in there. This is really sort of an experimental review of this product which is related to this product which I know Bosnian Bill recommended for lubricating your locks and so forth. This is supposedly a penetrating oil type of substance that doesn't leave a lot of crap behind and so I put a good bound in here, scritched it around, let it sit. It's probably been close to 24 hours. It's probably well more than the product needs but you can hear it's still a little crunchy inside but if I can decide how I want to tension it I don't think I want to do it that way. We'll see if it's more cooperative. I haven't really tried to pick it and actually I can still see some of that lube in there so we'll see what happens. This is a wafer tumbler lock and these typically are pretty susceptible to the old Bogota but it depends on how good the springs are. I'm not getting any sets so let's come in with something a little more precise and just sort of feel each. That was a set. That's promising. One thing with these locks is they, at least these Americans, but a lot of wafer locks give really pretty good feedback. There it is. So this old lock is now unlocked and open. So it's a QHF Quebec Hotel Foxtrot. Whatever you know that is. Series 10 American review. It's a keyway. Actually whatever is in there did dissolve some of the surface corrosion on this. It's old enough I'm not going to try to really restore it. It has this chain attached. It's kind of neat. I may put a little bit of rust remover on it just to clean it up a little bit. Maybe clean out the inside. I'll have it open. But yeah. So with my whopping one data point this stuff seems to work okay and I can tell you that I've used this stuff a good bit and it seems to work all right. I think WD-40 is still a better overall lubricant. But this stuff has the advantage it doesn't leave a bunch of greasy crap behind and dries up pretty fast. It's like alcohol based. So looks like it really wants to be stirred a little bit. So there you go. American Series 10 Wafer Lock SPP and a little information about this DuPont Teflon penetrant which you can find at the US at Lowe's at least probably at your local hardware store. So anyway thanks for watching. This is Alex. As always have fun and keep it legal. Cheers.
