2 part epoxy, I use it for all my meshing, pull starts and crank cases.
The old version I used was clear but the new lot I got is a metal colour. It does the job and can be peeled off when required without damaging anything.
Gizmo motors billet bottom end and lightened flywheel arrived after I cleared a £12 customs fee from royal mail.
Just need to decide on a top end now...
I stripped mine last night, hosed everything out, changed a bearing or 2 and rebuilt the front diff with some slightly lighter oil. I left the cage outside and the thunderstorm cleaned it for me
2-fold differential fitted with new internal bearings and pressure plates. Nowhere near as good as an oddified magnetic diff but I can afford this one lol.
