I have 54 3600 pu and I am replacing all the felt around the pass window. Don't ask me why I used a spray lube to make the window roll up easier. It just makes a rubbery mess after a couple of years. My question is what is the best way to install the vertical felt strip on the vent window? I know you can use a board and hammer but I don't want to distort it. I have used dish soap on motorcycle grips and that works great. What is you alls opinion?

Thanks Sharon
