Just a little tip. If you clean off the paint and use the same color plastic. After sanded just rub a little acetone on the rough areas and smooth it. Let it sit and it will look like new. You will not even have to paint the plastic part that don't get painted, it will look that good. I have been doing this for years. I will say this is the best way but a lot of work. I have been posting this for years and helping people out. Just do it in a good ventilated area.
great work
