*** Re Evergreen... I have a very good idea of the UK exchange rate vs the US dollar - its my business remember! You seem fixated on the sheet materials and have missed the point entirely. Evergreens strength is in strips and profiles, which is what led to its recommendation. - or are you just looking for a way to be contrary? Most of your post actually reads that way.
I understand WHY you are trying to cover errors with weathering, however the best result will always come from doing it right (or re-doing it until it is) and then weathering over a good result... its that simple.
No, its not common practice to spray over weathering. I already explained very clearly WHY you should not do that and the negative consequences of doing so. Consider texture and varying gloss/matt levels as being most of the effect. Weathering is always ON a surface, not under it.
Jaz, you said: "I appreciate you have shown your work. I appreciate you sharing your ideas. Considering all the time you spent on this thread you can have taken part
". OK, English has a unique ability to use emphasised positives to indicate negatives. Clearly you at least partly resent the contributions. I do not want to offend, so at this point I'll stop helping you.
What little I show of my work on MRF is there to demonstrate what I describe... I have no other reason for posting it. Silly me: I thought I was
taking part but offering more useful information by doing so than mindlessly showing I can assemble a plastic building that most 5 year olds could build... Thank you for reminding me how much of my time I have clearly wasted trying to provide something helpful...
(I have more than 50 loco kits in a drawer and half a dozen part built on the bench that are still there largely because I spend lots of free time helping other modellers and I do not waste what little valuable hands-on time that remains on assembling rubbish that is of no interest to me for any reason. I contribute to help, and I cannot imagine any form of time spent on that very poor house kit will help anyone more than the excellent example of sows ear to silk purse already offered by Stu)
In relation to your "toy" comment, that is a convenient mantra often trotted out, and is certainly not a reality: I actually disagree about as far as it is possible to disagree. It is an unnecessary defensive position taken by so many who do not have confidence in their work and that is sad to me.
I am sure you understood very well that the Lego example was just that, if perhaps a little extreme! (Going past Lego... You can by the way buy dead scale bricks to make models out of - they will drive you insane in the process but the buildings that result are to say the least unique and full of character - they are NOT toys by any measure!)
Like it or not, there is a difference between a scale model and toy. (Skilled modellers will often refer to their layout as their "train set" in a self-deprecating manner but that doesn't make them so in reality, nor do they really think of them that way - that too is defensive but for a different reason).
A bought item for a track-mat may well be a toy. A hugely expensive tinplate Marklin loco from pre-WW2 may have started as a toy but no longer is by virtue of its collectability... A hand-made scratchbuilt model, created with care to be a believable model representation of something in the real world is no more a toy and no less a work of art than a portrait painted by a budding Michaelangelo is a snapshot.
There is a world of difference in the intent and actuality of the efforts behind them... and in the result.
And... advice doesn't need a numbered, detailed rebuttal. You seem to forget that most of the answers there are in reponse to your asking, and many are in reponse to direct questions. I actually don't mind why you want to do or perhaps not do something or why you do it differently, advice is offered freely - so just accept it or not...
