Hi all,
Currently restoring a 1965' 6hp kiekhaefer twin cyl.
For the paint job:
ALL back to bare metal, nice and clean.
50/50 white vinegar and water.
clean with fresh water.
2K (2 pack or 'catalyzed') aircraft grade zinc chromate primer. Cured for 24h
3 coats of mercury phantom black - two thin dusting coats then one final one to give it 'shine'
Heat gunned primer after 20mins and made a MASSIVE difference.
Did the same in betwwen coats on phatom black.
Now its been 24 hours since the last coat of black went on and I can still scratch the surface and put my nail into it to reveal yellow primer.
How long should it be fully cured?! Why can I still scratch it real easy?!! Please, please any help will be much appreciated as Ive spend flippin' hours and hours trying to get this right.
Thanks Marc.
