Hi ! Is sikaflex the best sealant for putting between aluminium and the chassis before i put the rivets in ?cheers. Hope I've spelt it right !

Yes or you can use tiger seal.

I used a good quality clear silicone and its worked great.

I think there are various types and grades of sikaflex but yes, it's good stuff.

I'd steer away from the adhesive side of sikaflex. It's tougher than no more nails. There may be a time when you need to remount your body. It will come off in pieces if you've used adhesive.

Clear silicone as mentioned above is a good plan.

aren't the panels bonded to provide more structural strength?

If you want the sealant to be structural then use a PU (polyurethane) sealant, Sykaflex, Tigerseal, etc. Remember though, if it's sticking panels to chassis, it's only as strong as the bond between your paint/powder-coat and the steel. It will make removal very difficult though.

If you just want it to seal the panel to keep moisture out then use a silicone sealant.

DON'T use silicone, it's solvent is acetic acid which will eat your ally and rust your chassis in very short order

+1 use builders sealant if you don't want adhesive not sanitary. The neutral cure is also stronger than acetoxy cure iirc.

The best Silicon for just sealing is Silicon P, this is an inert sealer used for Polycarbonate roofing panels.

What do you call "short order"? I've just had a removable ally panel off that I'd sealed with silicone 6-7 years ago. When I peeled the sealant off it was still shiney underneath.
