Not only does this primer help paint adhere to the models' surface, but it's also very useful for filling small imperfections. It's extremely easy to spray, but the fumes are dangerous. Wear mask or use a spraybooth.

I bought this to try out on a 1/16 Dragon figure to fill some of the molding flaws. Worked better than expected!!!

Great primer if not the best, use it often. This is the grey.
