I think I my time is worth more than $3, so I bought it here at Amazon
Going from top to bottom worked well with me, as I worked an inch or two at a time to get snug fit on the door edge
Easy to install and a greta guard
Alex SHARP LOOKING AND WORKED GREAT Exactly what I needed, thank you!!!
Within the bottom of the groove there is an adhesive, so you want to limit smearing it within the plastic, it clouds the plastic and makes it more apparent on your door
cut the edging off at the bottom - I did not pre-cut as wanted to insure the that the stuff made it all the way down to the bottom of the door -Hence my recommendation to start at the top -work your way down
