As it happens, exactly what I am up to currently: I'm trying to do all the
bits I can before getting back to the resin, glass, and grinder.
IMHO there is only one scheme:
1/ acid wash (I use aircraft coverings/Stits stuff) - otherwise the
next stage is unreliable -use a brush and scotchbrite pads to make sure
every bit is properly cleaned.
2/ Alodyne wash -a chemical surface conversion to aluminium oxide -much
like anodising, which does the same job, but costs more. available in clear
or brown/gold (easier to see if you have good coverage)
3/ Zinc chromate epoxy on all external bits, or those requiring to be
bonded.
4/ spray can Zinc chromate for internal/ non bonded bits, and any
steel bits -easy to retouch.
5/ colour coats for anything you want to look pretty- pref 2 pack
polyurathane. epoxy goes dusty after a few years.
You can get away without zinc chromate on bonded bits, but resin on
untreated ali will always delaminate in time.
Zinc chromate is carcinogenic, so use a good carbon filter mask at least.
all the best,
Miles
