Im having a problem with water leaking into the trailer from the wheel wells. I've sealed the seams and the problem seems to be the actual gelcoat. I place a water hose on low and put it into the well starting from the bottom where the seam is and no leaks
till I get about 3 inches up. I dont see any holes or cracks but water comes through quick. then I tried it all along the rest of the well and its coming in there to. The waters coming in at the edge of the floor and well. When I put the hose on the edge, no water. I've tried sealing a small spot with spray on bed linner then used rubberize under coating . Slowed but no real help. Any comments what my next step should be ? I'm ready to use thick rubber pond linner to use as an actual physical barrier, not sure how I'll get it to stick. Thanks.
