Gate Remover Set

In stock

GATE REMOVER SET is a revolutionary product that reformed the conventional concept of gate-mark removing methods. It's GUNPRIMER's all-time best seller and widely used by modelers worldwide since its release.

Set Includes:


The three high-quality tools are enclosed to minimize the multiple steps for the gate-mark removing process and bring a perfect surface to completion.

Step 1: Removing Gate-marks

  • Use the RASER to remove gate-marks. The surface turns glossier than the original surface after the gate-mark is removed.

Step 2: Balancing Gloss Level

  • Use the BALANCER WHITE's green side to turn the glossy surface (Step 1) to a matte surface. This is the preliminary step before balancing the level of glossiness.

Step 3: Recovering Gloss Level

  • Use the RECOVER to the matte surface (step 2) to restore the gloss level of the original plastic parts. This completes the Gate-marks removal process with a perfect finish.


  • The name RASER is derived from combining the two words GATE + ERASER. It's a new concept of sanding tools that leaves no scratches when removing gate-marks.
  • Super-Nano Technology is applied to RASER v1.5 for improved abrasive performance.
  • With 400 grit force, RASER v1.5 can easily remove thick gate-marks to produce a clean surface without any scratches. Evolutionary super-nano technology provides a strong 400 grit force incomparable to any other similar products.


  • BALANCER is used after the gate-mark is removed with the RASER to balance the gloss level of the surface.
  • Depending on the user's methods, it can be used to process matte, semi-gloss or gloss surfaces.
  • Green side is used for pre-processing the surface before making a glossy surface. After using the green side, a super glossy surface can be acquired using the white side.


  • RECOVER is a finish touch-up polisher to restore the original gloss level of plastic parts.
  • It polishes the rough surface from sanding and adds a bit of an extra shiny look on the surface.
  • First, use the BALANCER's green side then use the RECOVER to retrieve the plastic's original semi-gloss surface. This step is crucial to have a perfect finish when removing the gate-marks and it's highly recommended for users who don't paint nor use top-coat after building.


  • The packaging case is designed as a reusable storage case for longer-lasting care of valuable tools.
  • Big enough size is easy and convenient to store several GUNPRIMER's tools and much more. (Make sure to remove the foam insert before using it as a storage case)


  • Residues stuck on the RASER, BALANCER, and RECOVER's surface can decrease performance. To remove residues, clean with water or masking tape. If cleaning with water, dry completely before using.
  • Tempered glass made RASER does not break during normal use. However, it can be damaged from external shocks and drops. Always store in a storage case when not in use.
  • Only use on plastics. Do not use on metals.
  • Do not wet the storage case as it's made of hard paper.




How do you properly clean this thing? It's wonderful but I don't want to gunk it up left over removed plastic.
Use tape. Preferably masking tape so you dont get tape glue on anything. Just press it down on to the bottom of the glass file and pull it off. Works really well!

Do these products become dull/unusable? Looking for a more economical solution than endless sandpaper.
The glass file in this set is unlikely to dull if only used on model kits. The sanding sticks, however, will eventually require replacement.

Best Glass File on Market

This is the best one, it only grinds the nubs, not the surrounding plastic, the grit pattern is unique, don't be fooled by people saying you can use any glass file, they will grind the nubs but they will also grind the surface when the nub is gone. The smaller size Raser is the best one, the large one is too big to get into most spots.

A must for special coating Gunpla

The tool is awesome, but works exceptionally well for coated kits. If you try to remove plastic from a part and miss, you scratch/scuff the plastic and risk taking the coating completely off if you persist! But with the RASER, you can touch the part and it won't scuff. Of course, you don't wanna go to town on it, but if you accidentally nick it, it won't be noticeable almost at ALL. The pictures in the description of how the finished product looks after Raser use is accurate. GREAT product. Only reason it's a 4 is that it's mega pricy and has already worn after just 1 kit. We'll see if it stands the test of time...

I honestly mostly us the Raser, but will occasionally go further with the balancer. Really hard to get into tight /small spots but overall really good. I find doing long passes in one direction works best for removing a lot of material fast and cleanly.
