There are many times when I don’t want to bother with the compressor and squirt gun to shoot 2 part polyurethane paint.
It could be too small a job; I don’t want to lug the compressor, or overspray will be a pain.
Awlgrip T0031 Reducer is amazing, but there are cautions.
First, it seems like magic. I see my horrible brush marks, and in a moment, they are gone. It’s smooth. But, up to what seems like a half hour later, it could form a drip. And, if you work outside, like I often do, it will grab insects or chaff for that half hour. Things to keep in mind. Painting closet/cabinet doors. Skythane 2 part poly.
