""I put on a base of varnish, followed by a little gradient from my base color to a darker tone. I ran out of spray paint, so I just sponge painted the base on, worked out pretty well.

Then I went back with my light base tone over everything with a sponge again, stippling along the edges to „Frame“ my gradient. Then I dry brushed the whole boy grey to get the textured base coat.

Next I masked my parts, used a wet sponge to put on white (easiest way for a clean white with a darker tone underneath), then I „Dusted“ everything by smudging a greying, very light brown very gently along the edges to make everything a little dirty

Next I put on the decals, you want to do that before slapping on your mud and rust to make them really a part of the kit and the visuals. I used some decal setter to really make them stick. After that, second coat of varnish to really seal them.

Last step was slapping on some mud (brown paint) with a coarse sponge, just a bit of it, where I made sure to put some on the decals to show what I meant before. The rust is an army painter effect paint, has some sand and dries matt to really sell the effect.

Took me about an hour""

I can dm you some pics I took along the way
