How NOT to open up 2017 Ford Focus RS Headlights with Permaseal!
On many permaseal lights, the cleanest, most "professional" way to open them up is to repeatedly heat them in the oven, then pry them open. Later the original sealant is scraped out, and new sealant is added to reseal the lights.
SCREW THAT! With these 2017 Ford Focus RS projector headlights, the ONLY way I'd suggest to open them up, is to cut the lens off! Watch and see why!
