For the turret on my Sherman I used Mr. Surfacer 500 stippled on and sanded right back.



It gives a good subtle cast texture. For added effect, and some scratches and marks. The Mr. Surfacer can be 'smoothed down' in spots using a dab of isopropyl alcohol on a cloth, and gently wiping it.

I got a rolled steel texture on my Tiger, by using a dental burr to make many shallow indents, then using liquid poly cement stippled on. You wait for it to dry, then sand it, and you get a great effect.

I'm looking forward to seeing more of your Pershing Tony!

Cheers,
Rik
