Not according to the instructions. According to the instructions, you basically have to remove them to scuff and prep or risk ruining your paint. Then, you have to give them two to three layers. This requires hours of prep, and it is a thin layer. Then, the instructions say to wait 48 hours. This is basically paint. Then, you have reinstall them. And paint will oxidize, chip, and pop. This is a three day job. And basically a masking procedure to cover up a problem.
I could waste some time explaining why most of that is fully incorrect and you've only come up with it to justify your position on temporary solutions, but it won't change anything, so just know you are wrong about most of it.
