Adding details and creating a concept for a hard surface model can take a lot of time.
Sculpting it first and creating a clean mesh afterwards can speed up your workflow but sadly the brushes in Blender have to be adjusted every time you start a hard surface concept.

That's exactly the reason why I created this Hardsurface Brush Pack!

What you get:

6x Different Brushes (+different variations for 5 of them (in total 10 brushes))
1x Sculpt (as seen in the preview)
1x HDRI

Note:
Created in Blender 2.82
