I have discoloured sealant above the cab on my lowprofile Rapido and more importantly cracks in the joint between cab and fairing.
Now to crux of matter what actual product does anyone have experience of for this application.
My view is we are dealing with dissimilar material ie Steel and ABS, GRP, TLA and large movements may be possible so a compliant adhesive is required. (more movement than with Solar panel mounting).
