Brush applied stain from the surface of a panel with a rag soaked in cellulose thinners before it dries. Go-ahead the panel to air dry once all traces of gloss own been removed. Lightly rub the surface of the panel with a fine-grade sanding pad to repair any marks in the primer and wash the panel thoroughly with automotive "pre-clean" thought before attempting to tint it again.


2. See for dye wrinkles that can materialize when a chemical reaction takes deposit between existing materials and advanced whitewash. They carry the appearance of minor, snake-like lines that eventually peel from the surface. Avoid too applications of emulsion and instead remove the affected panel from the vehicle.

Douse the panel with inundate to dump the active ingredient in the gloss stripper and dry thoroughly.

Apply cutting compound to the surface of the affected panel and polish back to a shine with an electrical polishing machine fitted with a foam pad.
