You don't say what kind of car but most require the gauges to be removed to take it off.
Look between the steering wheel and the clear plastic window for the gauges. There is a button on the steering column.
Depends on the kind of plastic, but try 100% clear silicone. It's good with many plastics. ( but in future ,please be more specific, - 'plastic' covers hundreds of different compounds.
Remove the screw that holds the trim piece in place the pull that out. then you can either remove the whole cluster or leave it in. I would just leave it in. Remove the plastic cover, there should be four clips holding it on. then remove the needles from the gauges make sure to remember where your fuel one is to. then remove the screws that hold the panels on and pull them out, then pull the old bulbs out, you may need to use a pair of needle nose pillars then put the new bulb in and put everything back on but turn your car on before putting the clear plastic back on to make sure your gauges are accurate.
When you open the hood of the car, there are 2 bolts that hold the headlights onto the car, one on the top of the headlight assembly and one on the front of the assessembly (facing outwards at the front of the car. Remove the bolts, and gently pull the headlight outwards and angle it upwards a bit, to clear the side body molding. You can not remove the clear plastic covers on the front of the headlight without ruining the seal, so I wouldn't recommend it; however, if your lights look cloudy and foggy, it is most likely the exterior of the plastic, and there are kits available at most car parts stores that will remove that oxydation and discolouring.
Clear plastic is waterproof.
polycarbonate is the strongest clear plastic.
Remove the seat. On the left-hand side (if you were sitting on your bike) there is a small, 3/4 inch square clear plastic "box". Remove the cover, there should be two 20-amp fuses inside. Not sure which fuse covers which circuit since we never received an owner's manual!
Have to remove the doorliner from the rear door. Remove the 2 screws that hold the black trim that covers the lamps. Then you can remove the clear cover and access the lamp.
visit your local cell phone store, they have clear, hard plastic protective covers for most styles.
I personally like thin, clear plastic laminating covers. This way, there isn't anything blocking your vision of what is laminated. It is also practical.
Try wiping it down with club soda. If that doesn't work, try white vinegar.
yes, clear plastic is man-made and is very bad for the environment
