Every cherokee has the holes in the fender wells were you open the doors you can see the tire, I was woundering what is an easy cheap fix to cover the holes, just done got 4 wheelin and my doors had about a gallon and a half of water...

 

wal mart sells long floats.... 3 or 4 ft long and about 6-8 inches around....they call em noodles around here.
They are usually near the toy section and are made of foam that floats.
Cut a piece long enough to fit in the open area. paint it black and shove it in.
Not very hi tech but it works.

 

Just spot weld a patch to cover the holes.
