I purchased this to refinish a wood stove that had been used outdoors for 10 years. After a good wire wheeling to strip the rust off the shell I wiped is with acetone and applied the paint based on the instructions. Air temp was about 75F. This paint is amazing ! Needs to be mixed well and it dries very fast so have everything prepped to go as you have very little working time before the paint starts to harden. Use disposable brushes. Paint won't drip off the brush if you are reasonably careful. Don't paint indoors! This paint is very toxic. There is another poor review posted however it was based on applying this to a brick fireplace. This product is meant for METAL not masonry. Highly recommend this for cast iron stoves. The color in the photo is charcoal.
