Eastwood Contour Polyester Primer Surfacer Gal

Eastwood Contour Polyester Primer Surfacer Gal

Product Review (submitted on July 25, 2012):

I carefully weighed 500 grams and added 25 grams of hardener, or "5% by weight" as stated in the instructions. I double checked this because it seemed like a lot of hardener. When I had used 2/3 of the gallon, I was out of hardener. Called and emailed tech support several times before getting a call back. After they checked with the manufacturer, they confirmed the instructions were wrong. Should have been 5% by volume, or just proportion the amount of hardener supplied with the gallon of primer. Can't believe they have not fixed the error yet.
