I have a few 3M red and green scouring pads that I bought from a painting supply store may years ago. While prepping a fiberglass hull for painting, I decided to give them a try. They did a good job in knocking off the gloss from the gel coat. Unlike sandpaper, they do not clog up when I used it on painted or primered surfaces. One thing it will not do is if you want to level or contour some filler. But for roughing up the surface, it seems to be doing a good job.
Are these pads good substitues for sandpapers? Any downside that I am not aware of?
