I used plenty - plenty of it to remove 20-year-old nail polish.
The result? Nothing. It didn't do anything at all. Unfortunately,
another failed purchase through the Internet.

It works quite well, but it needs a good sanding on wood, otherwise it will damage the new varnish/paint that will be applied. I don't know what would happen if I left it for many days after application.

It definitely needs a mask or better use it in an open space. I made the mistake of using it inside a room and even though the windows were open, it bothered me a lot.

Two hands of chalk paint color peeled off immediately. In this particular case, it didn't take much solvent. Be careful (besides wearing a mask, even those for the coronavirus, and gloves) before using it, it requires a good shake. Otherwise, pieces of the solvent will come out.

In another case, where there were two hands in wood, 50-year-old oil paint, apart from the heat gun that warmed them and they came off with a scraper, in areas with cables where the heat gun cannot be used because the cables will melt, the solvent managed to reduce the strength of the oil paint and come off more easily with the well-sharpened scraper.
