Been using Wurth adhesive to glue various bits together, but need some more, are there any equivalent tubes available on the High Street.

Prefer it to be black in colour when dry....

Ash.

Sikaflex 221 , sticks like . Got my last tube from our local Unipart motor factors

TIGER SEAL its in most motor factors

Tiger seal is good (despite being called a seal it's an adhesive ).... Sikaflex equally (but make sure you get the right one).

Other than that it's best to wait for the proper stuff rather than buying any old DIY general purpose "adhesive-sealant" gunk. Some are more sealants than adhesives and you want the proper stuff. Sikaflexing (as well as rivetting) the bodywork adds a fair bit of stiffness to the chassis. It'd be a shame to add the weight of a sealant but gain none of the benefits by using the wrong stuff.....
