This is a special reinforcing tape to recover the looseness of joints and moving parts of the mechanical model.


In order to reinforce a loose joint until now, it was necessary to adjust it by sharpening with an adhesive and then adjusting it by scraping or re-placing it, or by sticking it to the joint while cutting out a small tape by yourself.


This joint guard has been developed so that even these loose joint parts can be easily maintained for a long time.


Reinforcing tape has been cut into strips in six sizes to suit various shafts. In addition, it is a soft special tape with a non-slip coating on the surface, so it can reinforce the joints without applying excessive tension to the parts.


In particular, the joint parts made of PS, which are often found in the latest kits, are easy to loosen, making them ideal for such joints and movable parts.


In addition, a total of 1,054 reinforcing tapes are listed, so a single sheet can be used for several dozen mechanical models.


■ How to use

1. Select and paste a joint guard with a size that covers about 2/3 of the loose parts.

2. Use one to three sheets according to the degree of looseness if necessary.

3. When holding heavy parts, attach a small amount of instantaneous adhesive to the side of the tape and dry it. (See the video2 below)


【Important point】

1. Be sure to remove the grease and dust from the surface before applying. 

2. All parts are ready to operate immediately after the JOINT GUARD is attached. However, for ball joints supporting heavy parts, it is recommended to start after 24 hours after applying a small amount of super glue.

Great item

Great product. Have used on the RG rx-78-2 because of loose joints

Worth the price

These give you more control over how tight you're making the joint(s) than simply priming or surfacing. I hate gluing to tighten joints, so with this hopefully I'll never have to again!

I usually just do straight builds for my kits. So because I don’t prime and paint to help fix loose joints this is a great alternative. There are definitely other methods to be used but this one feels a lot tighter than the other ones that I’ve used in the past.
