That roof effect is seriously wierd!

Overall, a bit of a sorry tale, from which one might reach the conclusion that models produced this way simply don't lend themselves to being weathered.

A shame that your efforts to find a solution were not better rewarded.

I've weathered one of these for certain @gwrrob, it certainly didn't have the 3D printing pattern on the roof (that's what the lines are). I suspect the roof is the bare 3D Print.

Once I had started down this path I quickly realised that things were going to be different. Techniques that had become favourites were obviously not going to be sufficiently effective on the very uneven surfaces that I was facing. Injection moulded stock gives us nice flat surfaces covered with a nice satin paint finish and that was what I was used to working with.

I think that this type of product can be weathered, but it's necessary to think carefully about how you might need to tackle each aspect.

It's different!

Thinking about this, whilst there might be other approaches, could it be that this would just be a case of "lipstick on a pig"?

(Viz. it's still a pig!).

 I wonder how  the "old fashioned"  slosh the paint  on wipe off method wont work so well with that surface. 

 

I imagine you would have the same trouble as Mick has illustrated - if the surface is not totally smooth (and 3D printed stuff usually isn't) then 'wiping off' will merely highlight the undulations in the surface.

My favourite method!

The uneven nature of the surface means that any attempt at wiping off will probably leave material in the holes/ hollows/crevices/crevasses, so you both see it in the same light as I experienced it.

The effectiveness of capillary action is totally negated, so layers of pigment and/or paint will be the technique to rely upon until the technology gives us a suitable surface. I'm sure it's on its way!
