I want to fix a solar panel to the roof of the 101. I'd rather not drill any holes to avoid any possible leakage since it is now watertight for the first time ever!..
I have seen sikaflex mentioned before - but can anybody tell me if it is any good for bonding a couple of lengths of ally angle to an ally roof?
the panel is bonded into an ally frame, so i could easily bolt this into 2 angle rails. It only weighs 5kg but i dont really want it falling off at speed (well - what speed i can achieve!) or if i hit a bump.
Is there any particular type of sikaflex i should be looking for? it appears to be sold like locktite with loads of varieties all with numbers. Can i buy it from b+q or will i likely have more luck at a chandlers? Will it bond to bits of ally? - and i assume they will need to be paint free.
Or am i better off just trying to rivet my mounting railes into the roof? and using lots of paint and silicone to seal them?
