Weathering attempt
Posted by Foxy on Monday, July 27, 2020 5:51 PM

OK so I've decided to get brave and try building a 1/12 tamiya honda vfr750r.. Being only my third ever model I can see it being a bit challenging if not altogether out of my league... Anyway I've decided I want to try my hand at heat staining the pipes with some tamiya weathering powders.. I've looked on line but there's no real clear instructions on the process.. Prime/paint..do I need to clear coat if so gloss or matt... Weather.. Do I clear coat after weathering to seal(ive heard it can affect the weathering).. Any advice on order to do things would be appreciated.. Hope my question makes sense.. Thanks in advance...

I like using the soot color for WW2 planes.  I prime and paint and usually apply it over a matt coat.  I never tried it over gloss.  It does stick really well and it’s easy to use.  I don’t see the need to seal it with anything.  I don’t handle the model once applied.

Another bit of advice.  It comes with one brush.  A rubber like applicator on one side and a brush thing on the other end.  Once the applicator is used its hard to get the pigment off.  Use it for your most used color and q tips for the others or some other dedicated instrument.

Thanks for the reply... After what you say and some research.. General consensus is as you say, that as long as you don't handle then they don't require sealing... 

I have ordered a set of eye shadow brushes to eliminate the cross contamination of colours.. Thank you.. 

So my only real question now is can they be applied over a gloss finish successfully... As dull coat for an motorcycle exhaust really isn't an option..

I've used it on glossy metallic WWII airplane exhausts with no problem. It's true what you have read, the stuff adheres well.

Suggestion: go very easy with it and stop before you think you are done. Not sure what it would take to clean excess, haven't had to try....yet.

BTW, I'm late to the party and I see you already have some little foam pad things on order. I was going to mention I got a bag of them at Sally Beauty Supply for pennies each.

thank you for your reply.. I guess I'll give it a go then... If nothing else its certainly going to be a learning curve... Even if the lesson learnt is.... Don't get so cocky 3 models into your journey.. lol

Are you talking about chromed exhausts, and showing the discoloration that occurs (also seen on the exhausts of jet engines), or showing the oxidization that heat causes?  Or a mix of both?

tailpipe end = soot inside.

cylinder head end = bluish shiny finish.

I'd spray on super thinned blue enamel paint. Grade it with just a little black at the top.

 Modeling is an excuse to buy books.

I've drybrushed on red and blue stains of thinned enamel, but lately I have been using blue and dark red marker pens. It already goes on pretty transparent, so you can build up the stains slowly.

I will be spraying the exhaust mirror chrome so want to emulate the blue/brown stains on the down pipes  caused be the heat...

thanks for the suggestion.. However being a novice with an airbrush I tend to be a little heavy handed.. So thin layer may be a problem lol...

Nice looking bike BTW :)

Alclad makes Transparent Blue and Hot Metal Sepia colors for their line.  I used those on my Blue Thunder exhaust and the results look pretty convincing.

Ok so this is not only my first time using tamiya weathering powders but my first attempt at weathering full stop. Not sure if I've under done it or over done it but all in all I'm quite happy with how it's turned out certainly an improvement on my models with no weathering..

Looks like the effect worked well to me.

thank you... I've toned it down a little now.. Spent half hour debating if it was a little bold...
