Some may be aware that I’ve asked this same question here a while back but was wondering if there is a quicker and easier way of stripping factory mask paint off? I listened to one suggestion of dishsoap and a brush with rough bristles but it really is some work LOL. Besides, I tried this a bit on the neck area of my H1 based DP 08 and it didn’t seem to do anything. Should I use a different method since I’m dealing with factory mask paint? Thank you for your time everyone. 
dishsoap, scrub sponge, hot water
and LOTS OF TIME
Thanks for the response SPAZ. It will indeed require lots of time but just might pay off in the long run. 
there pretty much no way but you can paint over it because its smooth.

Aren’t the don post masks cast in white latex?
Alcohol should work pretty well. Not sure if that can damage the latex or not though. May want to check with someone who knows more about that before using something like that on your mask.
