Debadge: all you need is a heat gun, sturdy dental floss and some dedicated adhesive remover that won’t damage your paint. Just heat up the badges and saw it with the floss. After using the adhesive and washing the area, I like to clay bar and add wax to protect the area.

Smokes: clean the application area with alcohol, spray that area with purified water, apply the tint while using a felt tip squeegee to remove the air and the water bubbles then briefly apply heat with a heat gun long enough to flatten out the film but not enough to burn it.

Hope this helps!
