Chapter 4 - How to use Poly Putty

Poly Putty is a filler frequently used in model building, which mainly serves purpose of filling and pose making.

There are times we try to achieve a certain pose or appearance of a model, that we intentionally change the shape or model parts to make it happen. And that’s why we need poly putty, because its quality exceeds many model putties (For instance Tamiya Basic Gray Putty), in the ay it can be easily shaped and dries very quick. But not without its shortcoming of loosened joining with model parts and also potentially easy to crack.

How to Use:

Before you use the Poly Putty, it needs to be mixed with catalyst. Get Poly Putty (Brown color) out, then add a small amount of catalyst (Red color),
to blend them together, use a toothpick or swab to fully mix them together, after thorough blend it’s ready to be used for adding; Directly apply the Poly Putty onto the designated surface, because it hardens really fast, so don’t have to pause long before start drafting cuts, we use pencil to draw lines to plan the sculpting, wait for roughly 5 minutes then begin cutting, the process is considerable easy because Poly Putty is not fully hardened so it’s still soft,

take advantage of this status to remove all unwanted putty chunks. Another 10 minutes would make it completely dried, it’s the time for polishing, the technique is nothing different from regular polishing for model craft, after this step we can still easily add more texture details on it, tools like etching needle are suitable for this process. And we can recreate all details if we want to change the shape and pose.

Safety Reminder:
Please keep sufficient air ventilation and be careful with fire, because Poly Putty is a slightly volatile substance, and inhale it constantly would be the same as oil solvent, which is potentially dangerous to health. And this putty is also quite inflammable, so keep in mind to stay away from fire for your own safety.

Poly Putty vs. Other Fillers:

Compare with regular putty, Poly Putty hardens much faster and it doesn’t shrink after dried; Compare to Epoxy Putty(Mixed putty), Epoxy Putty is hard to polish on after dried because the hardness, but Poly Putty is easy to polish. As for Polyester Putty & Moli Moli, all three are quite similar in quality and how to use,

the only major difference is that those two are branded specifically for model building, so they are substantially cost more than Poly Putty.
But taking both the price and quality into account, Poly Putty is a pretty good balanced choice of putty.
