I got a tar spot on my Yellow car and it looks like penetrated into the paint, totally no idea what to do, may try to find the product you mentioned , keep up your good video, support!
you can try any degreaser and if the clear coat is gone and its not to big a hole you can put some touch up clear coat on. or if your paint is solid ask at the dealership for a color coded paint for your car so you can fill it in yourself its pretty easy if you dont shake your hands to much :-)
