After a lot of effort, I've finally got the lower fork tubes very close to a finish that I am happy with.
It took close to six attempts including a failed powder coating effort to get them to where they are now.
Unfortunately the original plan of powder coating them gloss black failed due to an out-gassing issue that created a significant amount of bubbling upon the finish. After having them powder coated by a friend of a friend, it was all too messy to get my back up over the situation, so I attempted to fix them myself.
I decided to simply sand back the powder coat with 600 grit wet and dry, to get it back to the blemish free surface that I'd originally had.
I utilsed the VHT roll bar spray paint and subsequently covered it as directed. I did however, manage to stuff up my hard work (more out gassing) after deciding to bake them in the oven to try to obtain a better gloss result.
Needless to say, after much trial and error, I now know the correct recipe to getting the quality of finish that I require. This process also includes a liberal coating of clear coat.
All that's left now is to remove any tape, install fork seals and re-assemble the front end.
