I cut a portion of automotive grade vinyl wrap around 140x145mm
Removed ancillaries from the fork tube and wrapped. Helps to get a second pair of hands and a hair drier to keep it mailable. The key part is keeping it square to the top yoke, the bottom doesn’t matter so much as the indicator covers it.
Then you bolt everything back on and job’s a goodun!
It’s a really cheap mod, but really effective I think
I have a load of the stuff left over, more than happy to cut some pieces and post them, I’d have to check postage costs for you guys across the pond though.
