Issues with parts are all about water in the IPA. I use 99% and get 4 gal for about $80. I also filter and distill my old IPA and bet ~91% from that. Order from https://www.amazon.com/Isopropyl-Alcohol-Grade-99-Anhydrous/dp/B01KK014F4?pd\_rd\_w=Vl8mN&content-id=amzn1.sym.deffa092-2e99-4e9f-b814-0d71c40b24af&pf\_rd\_p=deffa092-2e99-4e9f-b814-0d71c40b24af&pf\_rd\_r=DK5WTMTE9PFWSSYQXFFR&pd\_r...
Also, you may just want to check amazon. You can buy gallons of the stuff.
Good price. Some amazon options -
17.75/gallon if buying 4 gallons (71 dollars total) https://www.amazon.com/gp/product/B01KK014F4
30.00/gallon if buying 1 gallon https://www.amazon.com/Isopropyl-Alcohol-Grade-Anhydrous-Gallon/dp/B07L6MMV7F/
For resin work, I go no lower than 91%.
I recently, maybe insanely, ordered four gallons of 99% from Amazon for $70.
