I used this to spray Fluid Film rust prevention on the underside of my car and it worked pretty well. It seems to be pretty well made and it cleaned up easily. My only issues with the gun was that there isn't any way to control the amount or spray pattern coming out of it. Also, I have a small 3 gallon compressor and I wasn't able to spray for more than a few seconds before having to wait again for the compressor to recycle again.
