Working from the top corner down, adhesive in the groove of the rubber to grap the lip of the frame...not stretching it too much (pulls away from the frame) nor crunching it too much (wrinkles in the rubber on the inside of the cab) I press gently and tape in place every few inches.
Once the forward piller is done all the way down to the joint between the piller and the rocker, I go back to the top and work the back half all the way down to the joint where the striker plate piller joints up with the rocker....at this point, the entire door frame has tape every few inches...I've tweeked the fit as needes while the glue is wet and checked for no wrinkles inside or huge gaps on the outer face between the rubber and the steel. At the bottom, I've trimmed the new rubber about 1" too long.
Carefully, watching the lower corners to make sure they are both snug to the frame, I nibble back to create a butt joint that I will glue together.
A line of good 3M adhesive on the butt joint, stick it together and tape it till it starts to kick over....meantime clean up the kick plate with a bit of 0000 steel wool and comet. It won't take off the rust but it'll remove the stains and make it look good. I don't want a spanky new one....this ain't no Riddler.
The kick plate installed to hold the rubber and lower corners in place. Looks much nicer with all the lil boot stains gone. Just a whisker of shine and some rust in the corners so ya know its original 1965 not China repo.
Now, back it out into the sun, door open, let it all kick over a few hours while I clean up the garage and tools. Then, Drivers Side Door gets done but I gotta mow lawns and wash dogs today, so.....till next time.
