I am looking to use a brown wash over my Tamiya Panther tank. I am interested in the Mig products but they are enamel washes so I was wondering if that product could be used over acrylic paints? Does anybody have any experience with this product? Also, any suggestions on a good brown wash would be most helpful.

Enamel wash over Acrilycs dont give any problem

While you can apply an enamel wash over acrylic paint, I would suggest a coat of Future (or acrylic gloss coat) first.

While I have no experience with this particular brand, the rest I have used are completely safe over an acrylic base

i dont have that particular wash but i have some other wash from MIG and you can go straight over acrilycs like Vallejo,lifeColor or Italeri

Their wash as others have said is safe over an acrylic basecoat.

I find a semigloss finish helps with the flow.

Be aware that their washes are quite concentrated and can leave tide marks and stains/fuzzy edges around details. When I make my own washes, I do not make them quite so concentrated/saturated w color.

Their solution is to let the wash dry (+- 24hrs, or use a hairdrier) and then 'stump' (art term meaning to wipe back with an enamel thinner brush barely dampened ) the wash back into the seam/panel line or edge.

I know I am not explaining this very well, but their Youtube channel demonstrates this, as does Adam Wilder's channel in several videos.

I picked up the Mig wash (dark brown for German Tanks in Panzer Yellow) and it works great. Just make sure to wipe away any excess. Thanks for all of the advice.
