UPDATE TIME!!
Dustless blasters came this morning, five hour journey for them, three hours later they were off.
Its amazing how easily it strips the shit away, uncovered a bit more rust but nothing critical, they even said how nice the shell is, compared to what they are used to!
once blasted, phosphoric acid was brush applied, allowed to dry, before zinc primer was applied. going to leave it a couple of days to properly take before washing the shell out, and assess the bits that need cutting out!
had a tidy up while i had some space!
And back in the unit! I have some videos of it being stripped, il upload them to youtube and share on here later
