How is the window trim attached at the back and how do I get it off and on. That's the one part the paint shop did. They said it was filled with a body filler of some type and they ground it out when they painted. Now it leaks and the trim doesn't fit well.

If you don't use water how are you going to clean off all the bugs, slugs, gopher guts, tree sap, bird dog and deer [censored], dirt, tar, soda, BBQ sauce and beer?
