I want to paint the fork of the SR400 disc brake kit black.
In addition, I would like to paint another hub and brake panel.

I did sandblasting.

Before

After

But, when sand is shot for a certain period of time, it becomes clogged with sand.
So I went to buy plumbing at Benizen, a tool store in Kasai city to add a filter.
I bought the anaerobic plumbing sealant incidentally.
Benizen is amazing when writing product features directly with magic.
If you read it firmly, it is written in a small letter officially.

This sealant is very stinky but it is very convenient.
Because it is anaerobic, it only hardens when it is in contact with the metal and the air is blocked.
So, like a de-oxime type, it is not a thing that something evaporates and hardens.
It is early to harden about a screw part wanting I to harden, but can construct it slowly until I interrupt air.
Because it do not harden, I can wipe off the sealant which overflowed.
And the sealant on the inside of the pipe is low risk of floating inside the piping as a lump.
It is very advantageous in terms of reliability and construction time even compared with seal tape.
Especially useful for piping of hydrogen molecules which are small and leaky easily.

I added a filter using this, but the symptom was not improved.
It is not caused only by water droplets or oil mist, but water vapor melting in air seems to be a problem.
Should I buy a frozen air dryer?
It is very expensive.
