Review on Guardair 79SG Syphon Spray Gun by John Murphy

I was looking for a sprayer that could pump some waterproofing compound straight out of a 5 gallon drum for a perimeter fencing project rather than having to refill a small portable cup every 10 minutes or so. This sprayer worked great! I cranked my compressor line up to about 50 psi and sprayed about 400 +/- feet of fence in about an hour. Works right out of the box, uncomplicated and easy to clean! Yah, I will recommend for such projects!
