Tarp burn: Trial and error wisdom
Among the several adventures the PO has provided for me, an especially vexing one is the splotchy brown marks soaked into the front end cap, resulting from use of a tarp.
The natural first thought was leftover clear coat. Wrong. When stripper had zero effect, my son pointed out that the pattern of the marks, which looked like oversized pixellated maps of Asian archipelagos, was essentially rectilinear, like a fabric. Bingo: Tarp burn.
Then began several sessions with Nuvite F7 to gently dig deep enough to get rid of the brown. Here are a very few tips that seem to work:
1. F9 seems to scratchy and damaging for this purpose.
2. It seems that the F7 has a chemical quality, as well as being abrasive. Therefore, applying it and letting it sit for perhaps an hour seems to remove more color at one go.
3. However, leaving it on for an hour means it will dry, and then be balky to remove. I might just have invented a pro tip here: A light spray of mineral spirits before buffing it off seems to do wonders.
4. Lather, rinse, repeat.
That's all! Perhaps others know if these ideas make any sense -- or even better, might have better ones!
