almost all of my detailing is done with sharpie's, most people dont seem to know that sharpies use alcohol based ink, therefore a permanent marker really isnt, because you can remove it with rubbing alcohol and a cotton bud, I used to refurbish pos (point of sale) computers in a former life, and this is what we used to remove all the sharpie and ballpoint ink on the keyboards and monitors, takes longer the more time the sharpie ink is on the plastic as it slowly leaches into it, but if you make a mistake whilst doing the detailing, simply rub it with a cotton bud dipped in 91% alcohol (9%water) and it will remove it instantly and the alcohol doesn't react with most plastics we seem to use.

phil is correct, the doors over here in the usa are made from standard panels, several sizes, when we install them we just measure the hole and the manufacturer sends out panels to fit the hole, but also the bottom panel is the one that gets damaged so it is smaller, and stiffer than the others, and also easier to change, we have several in the workshop, all made of aluminium, but domestic doors are usually made of wood, but they are exactly the same design. hope this answers your question, I will try and take a photo of the inside of one of ours if that will be of interest, or you can look them up on the web.

over here in the USA I have found that "rustolium camouflage" ( it comes in a standard rattle can), is almost the same as rail grime, it is used to paint hunting gear, guns, tree stands, and anything else that will blend in with soil, its a sort of black-brown, put it next to black it looks brown, put it next to brown and it look black, I gave up several years ago with model paints,very expensive over here, so I either use car spray cans, or standard rattle-cans, its far cheaper and never had a problem with the nozzle's,, if one clogs up I bin it and replace it with the ones that I saved from cans that I emptied that did work. I also have a touch-up air gun I use to spray small parts in my shop, so if I need to spray something big, or a particular colour I need to mix up, I just lower the air pressure and the paint volume and it puts a very light coat on really well, but it holds about 6 ounces, and that will cover a lot of area, so not worth using most of the time on models.

Having followed this thread from the start, I think we sometimes forget just how big this building is (even in model form) perhaps it would be good to include a "oo figure" now and again just to remind us exactly the scale of your undertaking, I cannot truly express my admiration of your skills and patience in words, so I will just say "wow" and leave it at that. happy modeling Ron, may the plastic gods continue to smile on you!
