Was thinking about trying opti-coat on my wrx in the next few weeks. Trick is i already have 3m paint defender sprayed on the front part of my hood. The 3m works well and i really don't want to remove. My question is can the opti-coat go over the 3m? If not I can always respray the 3m but it would be easier not too. Also does anyone have any experiences with opti-coat they can share?
