Canopy

Lloyd M1
Where is it leaking from/to. It shouldn't be hard to identify where the water is entering. Either directly or capillary action is traceable.
I purchased a Flexiglass canopy for a different vehicle and although most of it was OK, water entered and dropped into the rear 100mm of the tub unless the vehicle was aimed sharply uphill at front.
Flexiglass in their wisdom made the underside of the canopy opening flat at each side, and trimmed with a flock like lining it simply wicked the water passing down the rear channel sides, forward into the tub and dropped down. They travelled 150km to fix it but had no idea how. Very professional indeed. After using their urethane to seal each side and leave a positive, drip like tail, of urethane as a drop point for the water to follow and exit past the tailgate links, all has been ok since. Capillary action was the problem.
Your problem may be similar as I believe it is fairly common problem with canopies. Any water entering at sides or front means it wasn't sealed at time of fitting and would need to be sealed properly.

You could try coating the inside of the canopy with talcum powder in the places you think it is leaking. Spray the outside and hopefully there will be a snail trail develop in the talc where the water comes in.

When finding the entry point of water can be complicated by waters ability to track through gaps and run along seams and channels before appearing inside. If you don't find obvious holes or gaps then thinking is needed to imagine how it could have tracked to the wet spot.

Ford dealers back in the 70's used to put an ultrasonic sound generator inside the vehicle and then use a detector on the outside to find dust entry points, but I don't know if anyone still has them.

My SIL had an ARB canopy fitted to his Colorado and they were unable to seal it.

I went for the SMM canopy which is all steel and has a lip the extends over the edge of the tray on both sides and the rear. The front has rubber gasket across the front between the canopy and front tray lip. I assume that this same gasket is also fitted on both sides.



End result is that no water can get in.

Just about all the other canopies just sit in the tray lip making it very hard to seal them.

Even though these weigh about 85kg, they are not all that much heavier than the light weight moulded ones. If you want to fit a roof rack on the steel one, they can carry the roof does not need to be reinforcing unlike the lighter ones.

Planning on driving on gravel roads or just a tarmac warrior.

If you haven’t fitted a tailgate seal kit, maybe the water is coming in there.
