that's good advise on the fiberglass or kevlar cloth strands.
I use fine teak sawdust mixed into any two part epoxy........that works
bomber, so well that I use teak sawdust mixed into marine two part epoxy (
west system ) to repair holes in concrete floors, it's that durable when
cured.
Should work pretty well on instrument clusters too.
Funny they made the instrument cluster cover out of indestructible
plastic.........I've never seen a broken one, but they made the instrument
cluster housing itself out of cheese. Bad-bad VW.
