Hi Greg!
Q: I recently acquired this car and noticed that it has some type of substance caked on along the roof seal. Looks like it's from a bad detail job from the past. What is it (polish?) and how do I get rid of it? It has a very dry, chalk like texture.
PS. I'm just entering into the detailing world and will be doing a lot of reading on your site over the upcoming months. I look forward to acquiring a full line of detailing products once I better get a grasp of everything
