sealant for rear light lenses ?

[V8NRG]

What sealant should be used for sealing the rear light lenses (Perspex covers) in place on a chimaera or cerb ?

I’ve seen sikaflex mentioned but there are a lot of different types ?

Where’s the best place to get it from ?

I stock Soudal 40FC which is the same polyurethane type as sikaflex,its £4 a tube,have suplied quite a few to my fellow Griff owners for sealing our lights,I can post if needed.
