Molding rear end shut ???? Need advice.

I was thinkin bout molding the rear shut on 2000 Kota....gonna put some caddy tails in i think.....i was told that there are problems with cracking (paint) along the seems because of the flex in the bed....Has anyone had problems with this....Or should it be ok??

the bed does flex quite a bit... but you can always use supports, and if you drag hard enought you will prolly crack a body line or two...

brace the shit outta everything before u put ur skin on and u should be ok, a little overkill wont hurt anything, because the beds really flex if u ever jack ur truck up at weird angles,sooo...here the more bracing the better
