### ⭐⭐⭐⭐⭐ Excellent
*by J***N on October 11, 2024*

Used to protect circuit boards in our campervan build

### ⭐ Defective conformal coating spray
*by F***S on May 25, 2025*

I finally got around to using this after several weeks. This was a disaster. First when I pushed the button to release the coating, it sprayed a black residue instead of clear. It then began to leak all over and finally just clogged up and would do no more. This was a waste of time and money.
