Hi James,
If you are going to do the hull much later, I think
you are on the right track.
Just use a cheaper fast dry primer to keep the rust
pitting at bay and blast it off when the time arrives for final
painting.
In immersion environments especially cold water and
with some flex because of the depth it is extremely difficult to get good
adhesion without sandblasting.
Just storing items on a shelf will not pose these
problems however.
Sincerely,

Hi Carsten/Jim.
I am intending to sandblast the entire hull
before final painting. But as this may be some time away, I was
just going to paint the installed viewports only at this stage, to stop them
rusting as i have only just made them. Is this pointless if i will need
to blast them anyway?
Shall i just leave them and blast them eventually
with the rest of the hull?
I thought that they would be ok if painted now,
but from your messages, it sounds like the ports need to be blasted as
well for paint adhesion?
Im sorry if i sound like an amateur but i am just
working this all out as i go along and there is nobody else to
ask.
Many thanks
James

Hydrodynamic Hatch Viewport Arrangement
That is what I will do..
Washing with soapwater than
Sandblasting SAE 2,5 than
Relius Oldopox Haftgrund ZHG, 321-0071 grau 30 um (Zink
primer grey)
Relius Oldopox
ARC, 325-9105 schwarz 125 um (black)
Relius Oldopox ARC 325-3109 rotbraun 125 um
(redbrown)
Relius Oldopox
Sealer, 354-3170 grau 50 um
(grey)
Relius Topcoat (deck) or antifouling (hull) in
blue
Washing is most
important - otherwhise the sandblast
push the smoke and dirt into the steel..
With this proffesional coat it will last
many years without work.
