Motorcycle stickers are durable. Generally, they can be used for three to five years without any problems. The main purpose is to protect the car paint, and the purpose is achieved.
The general steps are as follows. Clean with clean water and wipe dry the location to be pasted. Measure the approximate size of the sticker where you want to paste it, then draw it on the back of the sticker, and cut out the approximate shape in advance.
Tear off the back of the cut sticker (do not tear it off all at once), stick one side, that is, fix one end of the sticker, and then use a scraper (similar to a credit card) to slowly scrape from top to bottom, and tear off the backing paper while scraping.
If there are creases or curvatures in the pasting position during the construction process, use a hot Q (you can use a household hair dryer instead) to heat and stretch the sticker so that it will not wrinkle (note that you can't blow it all the time, you have to feel whether it can be stretched while blowing, and don't stretch it too hard, stretch it slowly, and then stick it, scrape and tear off the backing paper, and tear off the backing paper wherever it is pasted).
