The black will allow you to remove it, kinda, the yellow is very PERMANENT. I've used both the 3M and the store brands and seen little to no difference. Get the remover too, it is very handy and won't f'up your paint or upholstery.
Black 3M. There is a beter type of it avail @ NAPA et al that is the pro quality 3M stuff. A little more money but does seem to hold/apply better. Usually you need to ask special for it, not on the racks. One thing that helps is big clothes pins and masking tape. Wrap one side of the pin in the tape so it will not mar the finish. Use them to help clamp the rubber in place
For my FJ55 finding weather stripping was impossible, I nearly resorted to buying some generic stipping and gluing it on until I found a combo trim and weather stripping offered by Mudrack. At less than $3 a foot it is nice to be able to finish out the inside and weather stip the doors. No glue either, just cut it to length and snap it on. Very easy, very clean. If you have not purchased anything think about getting in touch with Gary at Mudrack.com and gettting this cool combo. I've looked all over and have not found anything that works so well. Check it out...good luck. D
