Swedish Ljungman AG42B Stock Finish

According to the SDS for Jasco, the active ingredient is dichloromethane. So it’s a different tack for you to try, for sure.
Like I said, it’s my go to choice and it’s mean stuff!

I'm not optimistic that the 1850 stripper will do any better than the Klean Strip.

I've always had a good result with 1850...have faith.

Thanks for hanging in there with me, and thanks for the guidance. I'll try the Jasco (I just made a trip 'down the hill', and wish I had read this before going out, and I would have dropped by the hardware store.)

Anyway, I'll report back after the Jasco (and, depending on how it goes, after the 1850), and bring you up to date.

Cheers,

So, did I get the wrong Jasco? I'm looking at the can now, and it says: Contains Methanol and Methylene Chloride. It doesn't say anything about dichloromethane.

[After typing the above, I went looking for an answer to this question and, finally, discovered from Wikipedia that: "Methylene dichloride (DCM, or methylene chloride, or dichloromethane) is a geminal organic compound with the formula CH2Cl2."]

So, I tried some of the Jasco on the same area that I have put the others, and it was just as ineffectual as the others...

Looks like my last hope is the 1850. And my guess is that the active ingredient there is the same Methylene Chloride/Methylene Dichloride/DCM/Dichloromethane/whatever... as all the others.

Bummer. I don't want to have to resort to sandpaper.

No need, next step is burning it off with a heat gun.

The 1850 will blister the finish right off. Use coarse steel wool to remove tough stuff. Then wash it off like it orders. You'll be happy, I stripped powder coat off aluminum with it...

The 1850 will blister the finish right off.

The safety data sheets are slightly ambiguous (manufacturers don't want their formulas plastered all over the place).
However, 1850 and Jasco read pretty much the same. They both contain "60 to 100% dichloromethane."
Jasco does fess up to a higher percentage of methanol, though. 10 to 20% compared to 5 to 10 for 1850.

Once could hypothesize this means there is more dichloromethane and less methanol in 1850 as compared to Jasco.

I will be interested to see if that hypothesis bears fruit on this rifle stock. There's a lot of known information on our old rifles...it's fun to chart new paths

I've never even seen Jasco around here and have used 1850 because it worked when I went looking for a reliable stripper. Don't know what they contain and haven't read the WHIMIS sheets... I can't imagine having this much trouble taking the finish off his stock...

[rcathey]

I can't imagine having this much trouble taking the finish off his stock...

Agreed. Just reread the thread and I can’t imagine any finish withstanding these attacks...unless....

How exactly is the stripper being applied? Regardless of the type used, you should cover the surface and keep it wet with stripper for at least 5 minutes - maybe even 10 or 15.
None of these are wipe on and wipe off products. They need time to work.

You can wrap the stock in Cellophane believe it or not and let the stripper work overnight. They're only active when wet.
