Running Board question

[rustbucket]

I posted this on Samba since STF was down, and got a bunch of snide remarks (that's why I don't post there in the first place!). So here goes again:

I picked up a new set today. The cheap Brazilian kind. Anyway, the ends of the boards have rubber that overlaps (goes past) the board by 1/2 inch or so. Should I try to glue that rubber around the bend, or do I just trim it even with the board? The rubber also seems to be not glued in some spots, what type of glue should I use to fasten it? I tried a little weather stripping cement, but I'm not sure it'll work. Contact cement seems too messy.

Thanks
