Pro GradeAcid Brushes - 36 Count 3/8 Inch Boar Hair Acid Flux Brushes

These brushes are great for applying flux to copper pipe soldering. They also work great for applying grease to threads or bearings and just toss in trash after using. Inexpensive and I use them a lot more than I thought. The brush bristles don’t fall out when using like some types do!

These brushes are great to have on hand. They are a very coarse bristle which is bad for fine detail but great for durability. They work for paint touch ups and dabbing grease. I use them to spread chemicals and assorted treatments as well. When you are finished dispose of properly.

Used for contact cement. Some bristles came out while brushing on sole. Check for loose bristles before using

Why did you pick this product vs others?:Good deal good people and fast delivery!

I use these all the time with my flux and patina for my stainglass. They are worth the price and hold up to the acid. Remember to wear gloves even with this brushes.

good value for DIYers for one-time use at a good price.

Versatile brushes for applying grease and other chemicals. Stiff enough to hold grease to apply to surfaces like battery terminals, bearings, and slide plates. Also for applying oil to mechanical joints. Many uses, enough brushes to avoid mixing materials.

I use these for projects using Epoxy Resin, JB Weld, Bondo, Grease, stuff you don't want to waste a nice paint brush on. and they work great. especially when working in tight spots. then just throw it away
