How to prep the defrosters on a 2021 Dodge Challenger

Method 1: If you’ve done all the prep work in the world and you’re still getting peanuts and bubbles along the defroster lines on this model, you could consider using a different type of film. Some films react better with some defrosters than others. The most common prep work strategy is to use a clay bar or steel wool with alcohol-based solution to clean the defrosters beforehand. You can also prep with wax and grease remover before moving on to the clay bar. Shrink very slowly and press hard and slowly with your squeegee. Some tinters like to turn the rear defrosters on as well to get the surface warm for tinting.
