An example of how things always surprise you. How in the world did cement sealer get onto the hood of this 2005 Altima? More importantly, who left the child unattended with cement sealer for this to happen in the first place? I learned a few good lessons with this detail. Firstly, cement sealer is some serious stuff. Secondly, sometimes you just have to get ballsey and go for it. Lastly, while this car was pretty tough, it wasnt tough enough for Meguiars products.
Here is our current condition after a wash using Megs Shampoo Plus, and a clay via Megs Agressive Clay. The first picture is of the hood and the second of a door.
Now that the surface is clean and free of any bonded contaimanants, its time to address the cement sealer on the hood. From least agressive to greatest and in this order, the foll.owing were tried with no joy : Citra-Gel, Goo Gone,Body Solvent, Mineral Spirits, Gasoline. Ok, at this point its obvious, cement sealer is pretty tough stuff. After speaking with Mike Phillips about the situation, it was obvious. The seam sealer had bonded to the hood. Scraping it off would cause the paint to peel (this stuff bonds X to cement, or cement to itself). I used a 80 grit sanding block to knock down the sealer. The sealer had a rubbery texture on the surface which gummed up the sanding block, sanding with water lots of soapy water as a lubricant was the only way to tackle it. Once the surface was sanded off, the sealer seemed very hard. I then CAREFULLY used straight Acetone to "eat" the sealer from the paint. As soon as the sealer starting to dissapate, I flushed the area with water. Below are pictures of the tools used, and the process.
