Pretty solid, easy to use
Would RecommendWorks pretty well, I used it on my wife's bike as a base primer, so far over a few weeks it still looks great. Also, I used it to stop rust on my bike engine's exhaust, and I know it isn't rated for high temperature, but it still hasn't bubbled off or flaked off even after a few weeks of daily use of getting the exhaust up to temperature, so I am pretty impressed!

Great for Warhammer IMO, SHAKE THOROUGHLY.
Would RecommendExcellent finish on the Warhammer Minis I painted with this, super crisp in the details while also self leveling out some unsightly mold lines. I purchased 3 cans and the only criticism is that I wish it were slightly lighter color but again that’s purely aesthetic. One thing I would recommend is to have a heat gun/blow dryer handy to help the accelerant evaporate, it helped with the otherwise slow drying time. From 45 minutes to 15 fully ready to paint. 2 light coats.

Some cans don’t work well.
Would RecommendSome cans don’t work all the way to empty. Took tip off and cleaned tube out with cleaner and did not help.
