Tamiya AS-12
Posted by mprest 1 on Friday, February 10, 2017 11:41 AM


I am building a pair of Revell Mustangs (2010 Shelby and '13 Boss). I am working on the Shelby first.

I primarily use Bright Beauty automotive sandable primers and on the shelby i put on a DupliColor grey primer sealer after about 3 coats of grey BB.  The sealer is a new process to me as i have only used it on the past couple builds.

I tend to opt to painting broad stripes versus decals so i hunted for a silver to match the GT500 logo decal that i would be applying.  After reviewing my inventory of SPOONS of silvers and buying a couple more i finally found the best match - Tamiya AS-12 Bare Metal Silver - not much metal flake at all.  

Following the primer and seal coat, the AS-12 went on nice and looked very good to my standards.  I figured that AS and TS paints are the same composition just that the colors are more suitable to air craft.  After 24 hours I started to mask and then it quickly went downhill, here are a list of concerns/questions: 

1.   When I pulled the mask up to realign it pulled up the silver.  So I tried to sand it down and then sprayed more AS-12.  I am thinking I didn’t let it cure, or perhaps not compatible with the sealer for masking.  Anyone use this combination of sealer/paint before?

2.   After respraying I realized I didn’t sand it smooth enough – there is a witness line so I need to sand again and spray so more.  Are these small cans of spray truly enough to paint 2-3 models as I have read on Tamiya site?  Has anyone really gotten that much out of a can or am I using too much?  I am already on my 2nd can for this model and now need a 3rd if I continue.

3.   When the members on here talk of a wet coat, is this just a process after misting a few coats where the paint is applied heavier, slower, and closer to the subject?  

The primary color was going to be Testors Grahite Metallic, I may just end up going with silver on silver and using the decals after all, but wanted to ask some questions before I make a decision.


As always, thank you all for looking and commenting on the post, I know there is a lot in this post.  I couldn’t be the practitioner I am today without this site and forum!

Thank you,

#2) Typically any time you pull paint off with tape it's due to lack of bite/adhesion! How was the surface prepaired before you taped it off?

#3) A wet coat would be the application of your paint almost to the point of the paint running...With uniform paint coverage and shine. Slower passes and a 50% overlap when spraying would be a common practice.

Read my post "Surface Prep 101" That should shed some light on adhesion.
