This is Mr Hobby Mr Surfacer 1200 Spray

Mr. Surfacer is a range of surface primers that can be used as gap and seam fillers as well as primers used by model makers and sculptors. There are three grades of Mr. Surfacer - 500, 1000 and 1200. Like sandpaper/emery cloth, the lower the number, the coarser the granules. Mr. Surfacer can be used for filling in bumps, scratches and pits. If the hole is large, use several layers, keeping each application thin so it dries thoroughly. Mr. Surfacer is also great for filling in seams. Once it has dried, you can remove any excess with a swab dipped in rubbing alcohol (IPA). The alcohol will soften Mr. Surfacer and rubbing it will remove the excess or it can be easily sanded using our range of MDC or Pro Modeller sanding sticks and sponges. CAUTION! Mr. Surfacer does dry very quickly.
