Hey guys, whats involved in getting the winshield & rear window moldings off without damage? any help? thanks

There really isn't much to do it. You need to buy a tool from the auto parts that is made to do that function. It slips under the trim and pulls it up and over the top edge of the chrome and that is how it unsnaps. Once you see the first unhook of one of the clips, you will see how it works. good luck and take your time.

Which car? 1968-70 b-bodies seem to have a TON of butyl sealer under the rear glass trim. It is easier to get them off when it is either extremely hot outside (and the car is outside) or use a heat gun to warm up the trim to soften the sealer.

Start with the upper windshield trim to understand first hand how they are attached.

Regardless, patience is key. If you are in a hurry, you can/will damage the trim.
good luck.

Attached is a pic of the tool for removal.

Work the hooked end between the glass and trim, move the tool along until you feel it contact clip. The hooked end is intended to be able to gently pry the trim clip outward to release the trim.

I have found it helpful to use this tool in conjunction with a wooden paint stick or tapered carpenter shim (like for doors and windows in a house) to gently pry the trim up after prying the clip outward.

*edit* Also, when removing window trim that does not use rubber channel seal/gasket, its a good idea to cover the back sides of the tool with heavy tape (like duct tape) so as not to scratch the glass.
