The underside of the car was coated in old underseal, dirt & rust. I have decided to clean it up as much as possible before painting on new underseal for some extra protection.
The first step is to scrape as much of the old stuff off as possible which I did with a putty knife. The wheel wells were coated in dirt so I used a wire brush. Once I had everything loose off I brushed on the underseal instead of using a sprayer, which would make a lot more mess. I’m happy with the finished product.
