Hello everyone, my wheels are back from paintshop and they looks so good, this time without any defaults :starry:

Then I've put some brake liquid in my front brake and rear brake, I was struggling to purge them, and I found some little details which wasn't helping me like the different "banjo screws" and a lot of dirt and rust in my master cylinder for the rear brake. But I finally won the battle and purge the front brake and rear brake and they're braking perfectly.

I've bought a radiator for 30 euros on ebay and tried to restore it, the result looks clean to me.

Why do they need to be sand blasted?

I would be careful blasting too aggressively, as the bearing mounting and sealing surfaces can be damaged.

It takes someone that is familiar with blasting aluminum engines parts to know where to blast - and where not to blast.

I asked them to only sandblast the outside of the engine because the painting is falling apart , but they're not touching the inside because the painting is good.
I told them to be carefull, so they will use micro sandblasting
