Product Review: Tamiya Putty Basic Type

Postby mangozac » Tue Feb 01, 2011 8:54 pm

Well I was at the hobby shop the other day picking up supplies and I stumbled across their new rack of Tamiya goods. There was some cool stuff on there but what really grabbed my attention was the Tamiya Modelling Putty Basic Type. It was AU$6.99 for a tube so for that price I had to give it a go:

The Tamiya Basic Putty isn't like your greenstuff or Milliput: it's a single part substance with the consistency of toothpaste (the tube it comes in is the same size as a mini toothpaste tube). Don't brush your teeth with it! It's intended for filling small gaps such as along seams on kits, or between laminated sheets for example on a scratchbuild.

You squeeze a bit onto a putty knife or sculpting tool and then quickly wipe the putty over the area you are filling. There will be a bit of a mess left over but once you let it cure (1/2 to 2 hours it seems depending on thickness) you sand it all smooth and you're left with a flawless finish. The instructions are all in Japanese so it's kind of just try it and see.

It seems like the putty has some kind of metal filling as it kind of catches the light. Remember too that being lacquer based it does eat into the styrene slightly so once you apply it there's no going back.

Before using the Tamiya Putty I was using some automotive spot putty (i.e. Bondo, but mine was a generic brand) for the same purpose and honestly it's about the same in terms of performance. Both seem to have about the same curing time. I know it's a stupid way to think but I feel a preference for the Tamiya putty purely because it's intended for modelling. Both types have a pretty strong smell though - if you have smelled lacquer thinner you'll know what I'm talking about!

The Tamiya stuff is cheaper, but it's also a much smaller tube so economy wise the spot putty is better. It'll take you forever to use the tube of Tamiya let alone the spot putty, so I figure that the Tamiya remains better value as there's none going to waste.

Tamiya - 32g - $6.99 - $0.22 per gram
Spot putty - 150g - ~$13 - $0.087 per gram
Yes that is a massive difference, but how long will it take to use 32g of it? A long time, trust me!

When you get adventurous you can also do advanced techniques with the spot putty, like creating a cast iron texture. I'll have to give it a go soon ;)

Conclusion: I give the Tamiya Putty Basic Type two thumbs up. As easy to use as spot putty but with that awesome feeling of using a proper modelling product!
Oh yeah I can make that....

Nice Post Zac,

Awesome stuff..so awesome they wont allow its sale in the USA anymore because of the solvents in it.. I have to buy it off eBay for Korean or Japanese dealers.

You can thin it with Tamiya extra thin liquid cement and paint it on like paint.. works great for filling in minor casting imperfections that way, especially on white metal parts.
Just have proper ventilation or you will get high as a kite with the stuff :mrgreen:

Seems to be more easy or more quick to use than green stuff for "hole filling" or "multipart model joints filling"

Tamiya seems to have a variety of putty. Anyone knows about the others ?

Tamiya 87027 Polyester Putty
Tamiya 87051 Epoxy Putty - Quick Dry Type
Tamiya 87052 Epoxy Putty - Sculpting Putty
Tamiya 87076 Light-Curing Putty
Tamiya 87095 Putty White
Tamiya 87097 Polyester Putty
Tamiya 89930 Poly Putty Hardening Agent
Si Dieu existe, j'espère qu'il a une bonne excuse !

It's certainly quicker than two-part putties, but fairly limited for use on figures and such, since you really need to be able to sand it properly. It sets so quickly that you don't get much chance to smooth it out over the join. Also, larger gaps, etc. will need a couple of layers to build it up.

The polyester putty/hardening agent would be some kind of two part system but I image would stink to high hell. I'd steer clear of it.

Light curing putty I have read about before. Obviously it sets from UV light exposure, but I can't remember what kind of curing time it has.

The epoxy putties are the same kind of thing we're all used to using, with a several hour curing time.
Oh yeah I can make that....

Great review, Zac.
Does this putty cure to a state harder than FW resin? The hardness issue came up in another thread here.
I've just accuired a Reaver and expect to do a fair bit of filling, so this info comes at the perfect time :)

I'd say it's not quite as hard as resin once cured, however I haven't found that to be a problem. As mentioned here, I used it on my SAW kit in many places with great success.

Just to let everyone know, I also did a review and simple instructions on the RA blog: http://www.resinaddict.com/blog/2011/06/materials-tamiya-putty-basic-type/
