Not sure how good it is, instant headache. Definitely don’t like it.
Used to clean before and after priming and it was good...cant use it on any paint..takes base off of ppg dbc, and omni plus...wont be using it again..primers and clears are great though..
I used hr 397 after I sanded before I was going to prime ( a prep-sol) after it dried while spraying I noticed it was lifting &I not going on smooth I wiped it off & re sprayed it seemed to be fine . I'm not sure if it wasn't totally dry & that's what caused it.
Gets the part so much cleaner then acetone
End your contamination issues with 397. Works as well or better than any other brand at an more attractive price point. Win-win
