    So I found the MSDS for 4020. And from what I can tell the only difference from 4012 is the Acetone. But the bottles could have told me that. The MSDS told me the correct mixing ratios :D. SmartSelect_20190311-110443_Adobe Acrobat.jpg So I'm on the hunt for the purest Acetone I can find (seems plentiful & cheap locally), and since I have over 36oz of 4012 on hand gonna take my graduated cylinders, and do a little mixing . I'll report back with my findings compared to the little bit of 4020 I have left :thumbsup:

    Its been stated before on the forum about adding 15 - 20% acetone per volume to 4012.
    Just a heads up for anyone who isnt aware..... MASK UP if you are using the 4020.

    Here is the link to the TDS for it

    It is supposed to be used in a paint booth with full ventilation and a respirator.

    Since 4020 is not intended to replace 4012, but mix with 4012 1:1, you could just do 5% acetone instead and not have to mix it twice?

    In fact older documentation shows 5 percent.

    I believe the switch to higher percent and mixing was due to the low percents storage times. Acetone can evaporate through the bottle at a slow rate. So they upped the percentage and let you mix it down on your own.

    7 percent has been great for me.

    That’s true, around the end of 2018 the documentation said 5%. I’ve tried adding acetone to 4012 without any problems. I didn’t notice any particular benefit, but that is as much down to experience and personal preference as anything else.
