First of all, if the depression is deep or the area is large (depending on the situation), you can "pull" it out first, insert the glue stick into the glue gun and heat it for a few minutes, then punch holes evenly around the center and slowly hit it on the suction cup.

Then use the residual temperature to gently attach the suction cup to the appropriate concave stress position.

Then, after the melted glue stick is cooled, connect the sucker head with a T-shaped connector, and pull out the sucker evenly and forcefully, so that the depression will come out slowly!

After using the "pull" step, start the lamp board and slowly "push out" the small concave area with the help of the lamp hook (this step is the most critical and technical step).

After passing through the "top", almost all the depressions have gradually disappeared, and then the slightly protruding parts are treated with the help of a rubber hammer (this step is not specific before and after the previous step)
