chuck540z3 Posted October 1, 2012 Share Posted October 1, 2012 Being a "Jet Guy" I know how to paint and weather a jet engine fairly well, but now I need to paint the short exhaust stacks coming out of the sides of a Packard Merlin for my current P-51D build- and I don't really know what to do. What sequence of painting and weathering do you guys employ? I was thinking of painting the stacks black, followed by a thin coat of rust colored enamel, then dry bush some sooty pastels to get the rough weathered look. Any tips out there on what the best method would be? Pics would be nice too. TIA Quote Link to post Share on other sites
Slartibartfast Posted October 1, 2012 Share Posted October 1, 2012 Go easy on the rust. Exhaust manifolds were 304 stainless steel, not cast iron or mild steel. Quote Link to post Share on other sites
DonSS3 Posted October 2, 2012 Share Posted October 2, 2012 I'm with Bruce, go easy on the rust. If you're airbrushing, I'd use a Burnt Metal metalizer. If brush painting, probably one variant of steel or another. I use Modelmaster paints, myself, so I've just use their "Steel" paint. I'm not sure what's out there from other manufacturers.

MikeC Posted October 2, 2012 Share Posted October 2, 2012 I paint mine in a reddish-brown colour mixed with a dash of aluminium, then when good and dry rub in graphite ie ground pencil lead. Gives a convincing (to me, anyway) dark colour with a metallic slightly "burnt" sheen. Quote Link to post Share on other sites
martin_sam_2000 Posted October 2, 2012 Share Posted October 2, 2012 (edited) Here is a close-up of the exhausts on packard Merlin( Its on a spitfire but its till a packard). AS you can see, they aren't really a rust colour at all. That said, I usually paint mine with a base coat of jet exhaust, then a VERY thin layer f rust to give it a bit of that brown colour, then dry bush a bit of black, and steel to give it some depth. Here is what mine look like before weathering. I don't seem to have a good shot of any of mine after they are done <_< Sean Edited October 2, 2012 by martin_sam_2000 Quote Link to post Share on other sites

Grey Ghost 531 Posted October 3, 2012 Share Posted October 3, 2012 I use Model Master "Jet Exhaust" and then touch the tops of all but the leading stub with gray pigment. After a flat coat, it looks the part. Quote Link to post Share on other sites

TonyT Posted October 4, 2012 Share Posted October 4, 2012 These are Griffon Spit ones All pictures by me, not how the whitish exhaust staining is not on the front stub, as it is not in the airflow of any stacks in front, hope they help. Quote Link to post Share on other sites

chuck540z3 Posted October 8, 2012 Author Share Posted October 8, 2012 (edited) How's this boys? Sorry if the pics don't show all the fine detail. From the top side.... And the full side, showing the exhaust staining better. Yes, the seam lines belong there..... Edited October 8, 2012 by chuck540z3 Quote Link to post Share on other sites
