RC Tank Warfare community hobby forum

what do you guys or girls (just in case) use to fill holes on the plastic parts on the tank ? im going to move the aerial from the body to the turret so want to fill the hole in but what to use ?

Tamiya white putty works well. You may have to fill the hole, let it dry, sand it with a very fine grit sandpaper (600 Wet or Dry works well), and fill it some more, as putty sometimes shrinks. (And, yes, there are and have been a few women here on RCTW; more would always be welcome.)

thank you will have a look for some

If a hobby shop isn't handy, spot and glaze putty for auto bodywork is good. Back the hole with a snippet of plastic card, fill, sand, paint and gaze in amazement!

there is also this type of glue, 2 components, can be drilled, sanded, etc. once dry, ideal for plastic, otherwise Tamiya Mastic carrosserie

I use a piece of plastic rod sized to plug the hole and cement it in with plastic cement.
Shave of sand smooth and then a spot of putty or CA then sand smooth...done!


Holes plugged with styrene rod on Abrams turret sides.

Ditto on the styrene rod. Sometimes if the hole is less than an 1/8" medium cyno works for me.

I'm with Barry and Dandy. Styrene rod eliminates the shrinkage issues. Large nasty irregular holes I tend to used a styrene backer and fill with Miliput. I hate the large shrinkage with Tamiya putty. I will use 3M super red putty for texture and filling 3D print lines. Although that usually means lots of sanding. Even some UV resin can fill print lines. Tons of ways to get rid of unwanted holes.

Two-component "finishing" car body putty is my way. One-part modeling putty like Tamiya tends to shrink.

I also use the styrene rod method. However, if you do not have any of the correct diameter then the other option is to stetch some sprue with heat like you would do making antenna for smaller scales.
Clip the tapered end of a section of stretched sprue and thread it through the hole to be filled, from the outside. Pull it through until it stops and is snug in the hole. Once set you just cut it flush and a tiny amount of surface filler and sand and it fills perfectly and strong with no shrinkage. Each streched sprue gives tapered ends for two holes.
