Painting epoxy primer on the Mini shell

I purchased a 300mm ventilation fan to exhaust the tent whilst painting however to prevent paint overspray from covering the fan blades/motor and everything outside of the tent I made a simple panel exhaust filter manifold. 

Some wire mesh nailed to the inlet side prevents the filter material from being sucked into the box.

The filter material is placed over the wire and held in place by a simple timber frame, making it quick and easy to replace when it gets clogged.

I did one final check over the Mini shell for pinholes (and found/fixed a few) then spent some time inside & outside the shell scraping off old seam sealer that was not removed from sand blasting. Any remaining seam sealer residue was wiped off with thinners. These photos indicate some areas in the boot and engine bay that had original red paint underneath the seam sealer.

To prep the shell for epoxy primer (with anti-corrosion additives in the primer), the following steps were completed in the boot and engine bay :

Sand with 240 grit sandpaper

Wipe over with wax & grease remover
Apply rust converter (30% Phosphoric acid) and manually scuff with red Scotch-Brite pad
Leave for ~20 minutes
Wipe over with damp rags (water with small quantity of bicarbonate soda (baking soda) to neutralise the acid)
Wipe over with damp then clean dry rags to remove residue, until rags are clean
Wipe over again with wax & grease remover

Masked up and ready for epoxy primer :

The fan and filter in place :

The upper engine bay and boot were painted with two coats of 2K epoxy primer. Note : Each painted section in this epoxy primer job was left for at least 1 day to dry/cure before moving onto the next section.

The shell was put back on the rotisserie and then the prep & paint process was then repeated for the shell interior, including the interior roof.

...and prep/paint again for the shell underbody, wheel arches and lower engine bay

...and again for the shell exterior

Lastly, the roof and rain gutters were painted.
