I've got a lot of work ahead of me. Some asshole used undercoating on the whole bottom of the car.You can brush it straight on it still flows out nicely that way. The s8 reducer does makes it thinner for spraying but i have no problems as is. When ur done use a shopping bag under the lid. Trust me it will bond the lid to the can right quick.
It's going on the under carriage does that change anything?It has no uv protection either so I would put something on top of it.
