This is my third try at painting a rust effect on a 1:12 scale door for a diorama.

Amazing! Thank you for showing us!

My favorite is the third one, I think it looks more realistic.

This is really great. This technique makes me rich.　Thank you ！！！Thank you from Japan

Yes the gray primer looked the best it had more contrast I have a similar project same colors and I'm looking for the same texture to make it look realistic thanks for sharing your different steps involved in a nice rustic finish. God-bless.

Thank you for demonstrating your experimental work .....as a lover of industrial work effects old metal ....wood....ceramics and distressed looks this is very helpful I just❤ it.......and will try a few of your methods .....hugs from Scotland 🤗

Very cool!

I love it.

Love it , I will give this a try on a Guitar that i am doing for a client

Peanut butter. Never saw that coming. Did you put a sealant over top? The paints you are using; are they acrylics or solvent based? That gray slight edge is perfect!
