In this great series on how to wrap a BMW M2, there is an amazing 2 part series on how to wrap a BMW M2 front bumper so be sure to check that out. During the main install, Dimas wraps the film under the bottom secton about a 1/2" or 2cm. Instead of applying an overlay piece of green to get full coverage he instead applies Sliplo. This is a very easy install of a product that helps protect the bottom of the bumper from scratches. Every installer should apply this as it's easy to do and it's a great upsell that adds extra income, avoids having to overwrap an area the customer won't see and it makes the customer happy.
