OP: Wish I could help, but can not. This is why I chose to use only Seal One (Frog derivative) in all of my handguns for a while.
Many guys seem to forget, or choose to ignore the direction to First wipe away any previous Petroleum-Based cleaner with alcohol, whether using Frog or Seal. It takes only about 10 minutes. Were "Gummed Up" guns first wiped very well with denatured alcohol-as directed?
Seal One has worked perfectly in the Sig P6, P228, CZ PCR, .380 Makarov for several months, now used in the 'new' Spanish Star BM (9).
This gel version is excellent.
"Gumming Up?" Absolutely No sign of this using Seal.
I started using FL when it first came out. Thats when the instructions (which changed a couple of times while I was using it) told you to heat the gun, or leave it sit in the sun before applying it.
I did degrease the gun completely before initially using it too, and followed their directions to a "T".
At first, I was using it on the Glock I shoot weekly. And often more than once a week. I clean what I shoot after each use, and the gun was being cleaned and lubed exclusively with FL, and it seemed to be working fine as a lube. As a cleaner, it was OK, for getting the fouling out, but did nothing for removing or dealing with copper.
They later came out with another product that was supposed to do that, but that was just more snake oil, and did absolutley nothing to remove copper. It actually looked like water too.
I never "over used" it either, and like anything else I use for a lube, it looks like the surface is "shiney", maybe barely "wet", and its not slopped on or flying off when you shoot them.
Since I was using FL pretty regular at the time, I started to use it on other things as well. Thats when the troubles started. As long as youre cleaning and appling it a once or twice a week, it seemed to work OK. Leave what you cleaned with it sit a little while, and it was a whole different story.
I first started noticing things getting really sluggish with my revolvers. Cylinders that used to spin freely, with barely a nudge, would barely make a full revolution with a good spin.
I then took a P38 that I had cleaned with it a month or two earlier out to shoot, and on the first round, the gun didnt/wouldnt cycle, and I had to do it by hand. I had to do that with the first mag, and into the second mag, before it started to heat up and the FL went back into solution and started acting like a lube again.
Things like the above seemed to be more of an issue with things like the P38, 1911's, anything with more "rail" contact. The Glocks I used it on, werent as bad, but still noticibly more sluggish.
It was around that time, I noticed that the instructuons had changed (no more heating the gun), and the formula seemed to have changed too. It was becoming more watery. The early bottles were more like a cream when you squeezed it out of the bottle, now it was more like a liquid. It also got progressivey more watery as time went on too.
I also notiecd that I was getting some light rust on a couple of blued guns that Id used it on and hadn't shot in about a month.
It was about then, and after about 10-12 months of using it, that Id had enough and stopped using it.
From there I went back to cleaning with Hoppes, and using Mobil 1 30w oil as a lube. As soon as I did, the guns cleaned up faster, and any sluggishness instantly went away.
Compared to most other things Ive ever used, it was the most expensive cleaning product Ive ever used. Something like $14 for a little bottle, or $25 (I think) for the "kit", which included a can of paste, and a rag.
The paste lasted pretty long, mainly becuse I didnt really use it for anything. The bottles, I was going through one to two a month. Didnt take too long to figure out that this was getting pretty expensive pretty quick.
I go through a 32 oz bottle of Hoppes every three months or so. That costs me about what one little bottle of FL cost me.
The Mobil 1, cost me around $7 for a quart, and Im still using the same one (its still over half full too) I bought when I quit FL, and thats been three or four years now. So do the math.
