2004 Mazda 6s Wagon ATX
🤦♂️Used a soldering iron on 450°, to melt it 🤣
So if anyone else trying to do it it's a good method, prying and soldering iron.
Glad it worked for you.
The conventional way is to heat the whole unit in an oven or with a heat gun. This softens the butyl sealant and then it pulls right apart. After our work is completed, put it back together with clips and reheat (oven or heat gun) to reseal.
How are you going to deal with that melted plastic?
