Neutral glass glue can be used. Neutral glass glue overcomes the characteristics that acid glue corrodes metal materials and reacts with alkaline materials, so it has a wider application range and its market price is slightly higher than that of acid glue. How to use:

1. Wipe the stainless steel surface thoroughly to remove oil stains.

2. Spread the glass glue evenly on the stainless steel surface, place the spray cloth on the stainless steel coated with glue, and then squeeze the other side with enough force to squeeze out the air, but be careful not to squeeze out the glass glue.

3. After the glass glue is cured, the spray paint can stick to the stainless steel.
