O-Mask EVA foam masking plugs (7pcs) for F-4B Phantom wheel bays, recommended Tamiya kits:
(61121) or others....

MASKING PLUGS: These laser-cut, foam plugs are designed to cover wheel wells, air brake bays, intakes, exhausts, cowlings or other areas of your model.
Made of soft, colored foam, these plugs are relatively chemical resistant and therefore, reusable.
Made to fit a specific aircraft model from a specific manufacturer, they simply slip into the open area, completely filling it, thus protecting it from overspray.
Some plugs are split into multiple parts for easier application, so the joints need to be covered by tape.
Although these plugs are made to fit a specific aircraft from a specific company, you may be able to use them on the designated model but from a different manufacturer.
These masking plugs are easy to use and are tremendous time savers.
We highly recommend this new product.
