SEM 39133 Flexible Primer Surfacer - 13 oz.

This product adhered well to the plastic bumper cover I was repairing, even without using an adhesion promoter. The key to avoiding the globs and silly string some reviewers complained about is to (after shaking as directed) initially spray on a spare piece of cardboard or newspaper. Globs did come out of both my cans initially. After a few second, a decent spray pattern commeced, and all was good thereafter.

Worked great on a new bumper install for a 2005 Honda Accord.

Fills in bumper imperfections perfectly

First the spray nozzle is cheap and doesn't fan out enough. It also had a tendency spudder on the surface that I was painting. So I had to keep stopping and clean out the nozzle. I really suggest buying a spray can holder. After three coats it did cover. The surface was very rough so I wet sanded it with 800 grid. And smoothed out the sputter spots. After all that it came out well. For the price I didn't seem to be that good except for the fact it's flexible which I needed.

Dem is a good product

Terrible. Even after shaking the can for a long time, the nozzle sputtered periodically producing blobs of primer. Coverage was pretty poor and so was the adhesion. I’ll probably need to sand it all off and start again using a different product.

We purchased all the spray products, from the adhesion promoter, primer, color coat, and clear coat satin finish. In addition to following the can direction, we also followed some very specific technique directions we found on the internet, about painting plastic dashboards (which was the project). Basically, follow all can directions, GENTLY and LIGHTLY WET sand the surfaces with 800 grit, dry, and clean well with alcohol before starting. Start with adhesion promoter, follow can instruction. Then spray primer, color, and clear coat in 2 - 3 very light coats, each, and when you finish all primer coats, wait 24 hours to start color coats, and do the same when color coats are done, and you are ready to clear coat the piece(s). We allowed all of that to dry for 48 hours, before reinstalling. It looks wonderful. Not like we just spray painted a dash. It's a hard finish, and no chips or scratches when it was re-installed in the vehicle. Compared to spray paint, it's a little pricey, but it was well worth every penny.

I had real tough time getting the paint to stick to my bumper. I tried this product, it goes on thick, dries to a sandpaper finish. I had to smooth it out with 600 grit. But, the paint sticks to this primer like glue. I highly recommend this primer for plastic.

Hides imperfections well dries fast and sands easily
