It can not be helped because it is cheap, but I could finish painting immediately. I do not care because there is no problem in particular. Because the legs get hot, I applied a shrink tube and took heat resistance measures.
The ring coating was peeled off by the third use. It gets hot enough that you can not touch the legs with your hands. However, since most of the use is outdoor such as camping, it does not matter at all. In case of being used in a living table etc., just to be sure, it would be safe to lay a hundred Yon stainless steel tray.
Once it was used for about 5 minutes, the paint of the ring was peeled off. Parker treated film is exposed. Especially, I did not heat up, the equipment I used was an ordinary alcohol lamp of AS ONE, and the fuel was also absolute ethanol. Also, feet tend to get hot, and it will not touch with bare hands even in about 5 minutes.
