Bob, the front and rear screens don't need to be removed, only the surrounding trims, which leave ample room for the paint to be applied properly to the windscreen pillars.
I look forward to seeing how the job turns out, as I will be looking to have my Marina Convertible painted later on in the year, and for me a quality job is worth travelling for.
I certainly won't be using the last person who painted a car for me, as I would like the car painted properly, and no skimping on preparation.
When it comes to the paint refinishing, you are only as good as your last job, and I wasn't impressed sadly.......
