I painted my 92 Dakota and took out the little rubber trim that surrounds the windshield. I'm installing new stuff, as the old piece cracked. I can't seem to get the new piece to hold in there. It appears the original piece was installed with silicone caulk when the glass was installed. Do I need to dig out the silicone and put in fresh silicone before shoving the new trim in? To be clear...this is the type of trim that is "T" shaped with barbs that hold it in. Thanks for any help you can provide.
