I used a plastic-lamination machine. It was a small one, so it fit inside the car well. I coated every square inch of interior surface with it. It's a little tricky on the vertical surfaces to coat it enough without getting runs untill it dries and hardens, but I found a hairdryer sped up the setting up process. I had to make sure the cd player was on my favorite song, on my favorite cd, and pushed the repeat button brfore coating the radio, because, ya know, it's impossible to change it now that the laminant set up, and got all hard and stuff. The next big decision....A/C on or not? If you lived in southern CA or someplace with a climate like that, it's no big deal....AC, full blast. Ditto for cold climates...heat, full blast. Because, again, after the laminant coating, you will not be able to move the controls.
The plus side is that now with just a quick wipe using a damp rag, it comes clean and shinny! I am writing this from my laptop, because....well ummm....I sorta laminated my door panels, without considering how I would get out afterwards.
Somebody please come help me....please?
