Will Sharpie show throug Akzo?

I am thinking seriously about switching to Akzo for the fuselage, at least for the front half due to its reputation for toughness. If I do I will want to prime parts in large batches. I don't want to have to guess which part is which after priming, though. Will Sharpie marker show through the primer like it does with the Stewart Systems Ekoprime I have been using?

Yes, as long as you don't apply the AKZO too heavily.

Yes

99% of the time I can read the marking. The other 1% I may have skipped marking the part .

Some times a have a part that's hard to read thru the AZKO but it not generally an issue. If you put it on too heavy it might cover up the markings but that's probably true with any primer.

Got it -- light covering, just like the manufacturer says.
