Painting sequence

I have to paint the interior of the car and was wondering if that should be done before or after the exterior painting.

I would have to mask off the openings where the windows go , which have not been installed yet. Which includes front windshield and rear glass.


Another question, would it be better to install the windows and roll them up then mask off. Not the front or rear since I still need to do the headliner. Just the side windows.


Would it be better to finish out the interior then paint the car or visa versa.

Thanks,

Lou

Re: Painting sequence

My vote, do the interior first. If you happen to get any overspray on the exterior it can be easily remedied.

Custom painters don't screw up! They just add more graphics.

Re: Painting sequence

My vote is to do the exterior first (like the factory did them). Roll the windows up and mask them off along with their mechanicals. After the exterior is painted, then paint the interior and lastly finish the interior. If you're really, really careful with masking off the interior, perhaps you can do the interior first, but do you have experience masking (rhetorical question)? It just seems easier to me to do it my way.

It's amazing how paint gets everywhere. You don't want to spend extra time redoing overspray. As an example: if you're painting the interior black and the exterior yellow, you don't want to have to try to remove exterior yellow paint from the finished interior black paint.

Re: Painting sequence

Along the same lines and excuse me MB for buttin' in, but should the front and rear window channels be painted body color (windows are out) or treated differently? If painted body color how long to wait before installing the glass? I thought I read some time ago that the glue will not adhere well to paint.

True. The glass will not adhere to paint.


BUT....


Urethane windshield adhesive/sealer will adhere as will butyl tape.

Re: Painting sequence

My suggestion is to paint the whole car at once. I would leave all of the glass out and make sure you paint the areas where the window felts go etc. You won't get as good of a job when masking. As far as the front and rear window channels go, they should be stripped to bare metal and sprayed with epoxy primer. You don't want paint on them when the urethane goes down to seal the glass. Painting them means the urethane will only be sticking to the paint and if it doesn't bite into the epoxy well enough then the thin layer of paint is the only thing holding your windows in the car.

There's nothing wrong with being stupid as long as you know you're stupid, it's when you're stupid and don't know it that you become dangerous.

They were finish coat painted at the factory, so why not now?

Because that is what the modern day guidelines call for.

I can't think of a single OE that doesn't say epoxy only on window channels when dealing with a repaint.

3M urethane says the same thing if I recall correctly.



What the factory uses and its methods are not always duplicated in the aftermarket.
