Tough choices ! I'd suggest painting the highest points value single models you've got, even if it's a case of getting basic colours down and bases done and then come back to do the fine detail at a later stage.
Also, since your life seems to consist of fixing ships with a grubby white over red colour scheme, I reckon you should do some supporting marines of Imperial Guard from a custom formation with those colours. It might look good 😁
Hahaha, love that idea! Red and white and very weathered.
Hahaha! My Imperial Guard are already red so that's not too far off really.
Might be a beotch to paint white on the red though. We shall see.
I have 3x Leman Russ tanks, 2x Chimeras that I want to convert into Basilisks, 1x Valkerie and around 50 troops.
