307 on-glass spoiler

friends Is there a place in Istanbul that has a smooth workmanship including mounting paint that makes a 307 spoiler, preferably like a European side man? or where did those who have it done?

You can have a simple operation everywhere.

The operation is simple, of course, silicone + paper tape. mold is important I bought 106 gti spoilers before neither did the paint properly nor spoiler mold was good

Generally, the spoilers made afterwards are shapeless, they look pretty like idle, but after assembly, I do not know the original like it is definitively.
