One thing I would wonder though...would all the nails have a prominance on the timber wall? I imagine that at one point in time, they would have sat fairly flush to the timber and be nearly hidden by paint. Despite the flaking paint over the ages, would some nails still be masked over by the remaining flakes of paint, or be deeper set after the clumsy-overzealous carpenter had belted them in? Just wondering if the nail pattern looks too regular, and needs just a few to disappear under paint, or rust out all together.
THANKS for the suggestions/input! Some of them are flush ... most of the ones that "stick up a bit" only do so by about 1 or 2 thousands of an inch (which actually makes it a bit easier to go back and paint them).
So, next steps:
-- Go back and dot the nail heads with steel and rust tones. Those that lie in areas where the siding paint has been chipped away will just get some rusty detailing.
-- After the nail heads have the first coloring, I can go back and sink more of them flush. The mat varnish is a light adhesive, and a little push with the end of a drill bit will sink them easily ... but that probably won't be necessary, as the crackle paint (next step) has a fair bit of thickness to it and will likely form a fillet around the edges of some nails.
-- Then I'll go back with the various crackle colors and inks ... as mentioned above, the crackle paint has a fair bit of thickness ... so some nails will more-or-less disappear and many will become more subtle ...
-- And, if I manage to pull this all off, all those nails should add up to a rather subtle effect that adds depth and detail without becoming a focal point. Maybe I'll do an "interesting" bent nail or two on the lower level, more in the focal area ...

Russ, please mark this down as self analysis for the year...

If I'm ever forced to put a string of Christmas lights back into one of those little plastic nests and get that to go back into the box, I'll certainly have a psychotic episode ... the nutty business with the nails ... well, just like basket-weaving in the looney bin ... while looking forward to a little tapioca and maybe bingo later.

Wow, I am glad to find nuttier, er, more detail oriented folks than myself! Nothing like a laserboard on rye after all that hard work. I am also glad to see more progress.
Yes, well ... meanwhile, THANK YOU too! IIRC, you used the approach of treating various siding boards individually prior to assembly ... I did that here and think it will make a huge difference in the final appearance. Or, maybe I picked that up somewhere else, who knows? I think it was Chuck's fault.

Sorry , Chuck , but it is official . You are the nuttiest fruitcake of the lot . And long may it last , Nick
Yeah, not sure I'm up to the challenge of doing 1/35 scale wasps nests in the eaves ... and it's always nice to know there's someone nuttier out there. Nice try, Chuck.

Cheers,
