Rust-Oleum 254863 Automotive Filler Primer Brush On, Quart, Gray 32 Fl Oz (Pack of 1)

The Rust-Oleum 254863 Automotive Filler Primer Brush On is a gray primer that is supposed to build up and fill small imperfections, acting as a base coat for applications of enamels, lacquers, and urethane products. However, based on the reviews, it seems like this product is not very effective as a filler primer. Many customers noted that the primer was too thin and had low solids, making it difficult to cover even small dents or scratches. Some even compared it to acetone or a liquid thinner/waste product. That being said, there were some positive reviews from customers who found that the primer worked well for their needs. One customer reported that it sprayed smoothly and dried to a smooth finish, while another noted that it did not require any thinning and adhered well to metal surfaces. Overall, it seems that the Rust-Oleum 254863 Automotive Filler Primer Brush On may not be the best option for those who are looking for a true filler primer that can effectively cover small imperfections. However, it may work for those who need a primer that adheres well and dries quickly, provided that they are aware of its thin Consistency.
