Easy and convenient. I could stick the protective sheet from the first time without failure. Although it is not used in rainy weather, it is good to be able to clean the inside of the shop without fear of wet tissue.
It is used in a place lined with aluminum thin plate and exposed to outdoor sunlight / weather and rain, but it is durable and there is no such thing as the protective film hurting or water soaking. It is handy because it can be produced easily and color riding is also very good. It fades slightly in about 3 years, but it does not become so bad.
