Drip moulding idea, looking for opinions .

After reading several threads on this continual problem with them coming off, especially in car washes, and now looking to replace mine for the second time in 2 years, I had an idea and would like thoughts on whether it would work or not, and why if you don't think it would. I was thinking about going to one of the bedliner shops and seeing if they could spray bedliner in the channels. Couldn't they tape it off and spray it flush with the roof? Wouldn't take much im thinking and should last? Am i missing something that would make this not an option? TIA for any thoughts or ideas.

 

No opinions on this working or not?
