Two more customers for Green Village Computer Help... No sketches this time around. I've been ill, which was partly brought on by working in cold weather to remove the corporate logos from the car I bought from Net Access. I'll share what I learned here, in case any readers should ever have to remove vinyl lettering from a car:

1. Don't do it outside in cold weather, if you can avoid it.
2. You can use a heat gun or hair dryer to soften the letters. Cold vinyl is brittle and hard, paricularly when it's old. If the vinyl is too warm, it may pull apart like taffy when you try to lift it. Adjust the heat gun / hairdryer accordingly.
3. A scraper with a fresh razor blade is the best tool for removing lettering from a windshield, assuming that there's no tinting or electric heating element overlays on the side you're scraping. Under duress, I found the razor blade to work better than any plastic scraper on the painted sides of the car - it worked so well I didn't even need the hair dryer. Against this, there's the risk of scratching the paint or slicing your fingers open, so I'll refrain from openly recommending the razor blade. There's a product called Undu Adhesive Remover that comes with a plastic scraper tool which I also found useful.
4. The Undu comes in too small a bottle to be effective when removing large areas of lettering, so I used another product called Goo Gone. It worked fairly well, but had to be given some time to soak in for maximum effectiveness. I wound up loading a paper towel with the stuff, passing it over an area, waiting a minute, then using a scraper to lift off the loosened adhesive, at which point the residue could be wiped off with a second paper towel moistened with Goo Gone.
5. The Goo Gone needs to be washed off with soap and water, or it will leave an oily residue. My advice at this point is to just bring the car to a car wash.

Until!
