    Got some 2k primmer overspray I need to remove. Acetone, Goo Gone ain't cutting it with a rag. I've used fine steel wool in the past but this is a perfect new windshield I don't want to hurt. Razorblade, Scotchbrite, some other chemical? Getting conflicting info on the www.

  2. Get a clay bar, best invention ever. When I painted my T I got overspray (light blue) DOH!!! on my folks TWO new cars (red and white). With a little soapy water and a clay bar it wiped right off, even on the gl***.

    Hello,

    Overspray comes off just about any surface with lacquer thinner. It is stronger than acetone and is the last resort to remove something like dried on spray. But, if lacquer thinner drips on something, it may melt the stuff. Use a pair of gloves, pour the stuff on the rag and wipe.

    If the stuff does not come off in a wipe or two, then drip some lacquer thinner on the spray directly on the gl***. I have a clay bar and for me, does not work on something like overspray.

    We got my wife's other older station wagon back from the body shop. They had to spray the rear door and got some on the gl***. No one saw it until I cleaned the rear gl*** to go somewhere. Then I noticed the over spray. I wanted to use the single edge razor blade, but did want to accidently scratch the gl***. So, several drips of lacquer thinner on a rag and the spray stuff came right off. YRMV

    Man, 0000 steel wool and some gl*** cleaner, gets all surface containments off and works perfect on gl*** and stainless trim etc.

    If you use razor blades, just be sure they are new and you might use 2 or 3 to keep them that way. I have never scratched gl*** as long as razor blades were sharp.
     
  12. It's what professional detailers and body guys use. I learned it from a good friend after the previous snafu.

    A buddy of mine ran a heavy truck body shop and also built about one custom car a year. He also did custom upholstery. Lacquer thinner was his go to cleaner for everything. He washed his hands in it most days before he went to the tavern (attached to the body shop).

    Going to the tavern was just a continuation of a day in a paint shop. Never knew who didn’t. Most are no longer with us…

    When using razor blades on gl***, use a spray bottle with some soapy water as well. Don't need much. Just enough to lubricate the process a little.

  22. Gl*** is impervious to paint. Gl*** is "harder" than paint so s****e it off and use rubbing compound to polish off any residue. Razor blades are "harder" than gl*** but you would have to be a total putz to scratch the gl***. Just ask yourself if you're a 'total putz' or not.

    Not rocket science, If you are not satisfied after the razor cleaning, get some gl*** polish from the Eastwood Company and polish the gl***. It will look great and be super smooth,

    Fibergl*** oxidation remover works as well.

    Razor blades with a little water are the cheapest way to remove overspray from gl***.

    Like most chemicals that used to work well, what they call lacquer thinner these days isn't anywhere as good as the stuff from a few years ago. Its probably better to use for your hand cleaning then the old stuff was though.

    I use razor blades for lots of things, including removing stubborn bug splats from the windshield. Be sure the gl*** is clean and the blade is sharp with no nicks. I've never scratched the gl*** doing this.
    Get yourself a single edge razor blade s****er and a pack of blades and you're good to go.

  27. And soak it with gl*** cleaner. Helps prevent the scratches ;)

    Clean, new razor blades, doesn't hurt to spritz a little Windex on there first to lube the blade. I would not want to put any chemicals or thinner real close to my fresh primer or paint for fear of loosening it up.
