Spru Goo – Simple Yet Effective Way Of Filling Gaps On Plastic Models

Spru Goo is a word you have most likely would have heard banded about in the plastic model-making world. This handy product however is not something you can buy in a shop.

Spru Goo is in fact just glue mixed with old spru. Most model makers make it with the offcuts of plastic and frames that parts of kits are shipped in.

All you need is an old bottle or jar, some regular model cement and plastic. Mix both of these together in the pot and leave them. The cement then melts the plastic to create a plastic paste.

Using spru goo is easy too. It can be applied with an old brush or with a toothpick. Some of the big advantages over regular model fillers include ease of sanding.

As the material you are using to fill gaps is plastic, it is much easier to blend and sand to a good finish.

Of course one of the main advantages is it is pretty much free as it is made from things model makers use all the time.

Put simply, having a pot of Spru Goo to hand is certainly recommended for anyone looking to achieve a better finish to things like model planes.

Spru Goo A Simple Easy To Make Consumable

There is no real science to this versatile consumable. In fact, how thick or thin you want it really is down to personal preference. However the thicker the goo the harder it is to work on smaller areas.

Aside from filling gaps, I have used Spru Goo made with clear parts to actually bond two parts together. When building ships the goo helps with adding some extra strength to the model’s core construction.

Other actual applications it has been used is to fit landing gear to planes, adding that extra security. While the clear plastic version has also been used to fit clear parts.

But where Spru Goo really comes into its own is filling gaps or hiding seam lines. All you need to do is paint this stuff on, let it set then sand away. It may take a little longer to dry but it certainly provides a much better finish than regular filler.

Should you not have a spare pot or jar you can make Spru Goo up in small amounts. Just remember when you mix the two parts needed not to create your mix on a plastic surface.
