Bugs will love the oat bran !!!toggle quoted messageShow quoted text
The hard core weathering method is to use table salt on top of the undercoat, final paint, then rub to release the covered salt..
Any salt if scattered in the process won’t feed nor attract any ‘wild-life’.
I’ll bet that much the same effect as using oat bran can be achieved by using coarse ground salt like a canning salt. That will notch up the table salt effect with no possibly edible side result of the indoor environment.
Between the finer effect of table salt and the coarser effect of canning salt, I think you’ll have the range of weathering effects you long for.
Best to ya,
