  • Hi everyone, I'm I.R.O. The title may mislead, but the technique shown in the video will show you how to make nub marks less visible on gunpla without painting. This technique can also be used for removing seam lines. Hopefully this video will be useful.
    As noted in Disclaimer, this technique will not work on models that are coated in gold or titanium.
    Gunpla: HGUC 1/144 RX-78-2 Gundam
    Tools: Tamiya's Plastic Nipper, Godhand 2mm 400 Sanding Sponge, Godhand 2mm 600 Sanding Sponge, Godhand 3mm 800 Sanding Sponge, Tamiya 1500 Sanding Sponge, Godhand 3mm 4000 Sanding Sponge, Godhand 3mm 8000 Sanding Sponge
    The BGM used in this is "Classic Rose 2" from TH-cam's Audio Library.

    I recommend beginners stop sanding at 800 or 1000 grit and just topcoat everything in matte. It saves time and the entire kit will look uniform.

    Having just started into Gunpla this is really helpful. Did my first HG the other day and my sanding was definitely the part that took the most time and the most effort. I just need to widen my grit range and commit to the full send. Don't worry about scuffing up the body around the nub mark just clean it up with more smoothing.

    • @i.r.o.4456
      @i.r.o.4456  ปีที่แล้ว +7

      Really glad to hear that! However, this method is only if you're planning to remove the nub mark COMPLETELY. If you are planning to paint, then you can stop the sanding at 1000 grit, or if you plan to do a top coat, then 2000. Either way I hope your future projects will be fun!

      I will need to update this tutorial since I’ve noticed this method is a bit out dated. However, if you’re using higher grit sanding material, then you should be fine since it won’t sand the surface too much. It’s only the initial sanding process you should be careful

    At 1:31 I notice that the bevel on the edge of the piece is a lot thinner after sanding, is that just the trade off for removing nubs? I don't wanna sand down so much as to effect the curvature of the model.

    • @i.r.o.4456
      @i.r.o.4456  3 ปีที่แล้ว +2

      I want to say that’s the lighting since I checked the part again to see how much it’s been sanded, and found it’s not as thin as shown in the video.
      So I’ll deserve a dislike for bad lighting and photo.
      To answer your question, unless you heavily sand the surface starting with very low grit, you can easily avoid the situation you mentioned. From 800 grit, it won’t sand too much of the surface to affect the curvature.
      Sorry for the misunderstanding.

    Are these enough? Or do I need to add more grits?

      In my experience, there wouldn't be a difference of the sheen if you don't polish it to 2000 and above. However, you might notice smaller scratches on the surface if you don't polish it to 2000. So try it out on a random plastic spoon or something and see if the tiny scratches is noticeable enough to bother you. Good luck!

      If the flat files you have range from 400 to 2000 grit, then yes it does! The last step that does polishing, if you can find a flat file that uses 3000~8000 grit file, then you can also use those as well!

      Yes and no.
      Yes- the sanding grits between the two materials are the same, therefore even if you use two different products, you will still get the same result
      No- Sanding sponges are optimal for rounded surface, and sanding papers for flat surfaces. There are some products that allow you to vary the use between two surfaces, but the general differences are as such

    Hi, maybe you can help me with something: I am building my first gunpla in 20 years and Decided on the HG RX-78-2. When I sanded down my sprue marks I noticed that some of them actually got darker, and now there are dark spots in the plastic. It's hard to see, but if you get close and look for it you can tell. I used mostly 800-7000 grit Infiny sanding sticks depending on the part and how bad the marks were that needed to be removed. It almost looks like the plastic has been slightly burned. or maybe took on some color from the dark sanding sticks. Have you ever experienced this?

    • @i.r.o.4456
      @i.r.o.4456  ปีที่แล้ว

    The problem is that when you cut the part out of the runner the thickness of the nipper blade pushes out the part sideways 1-2 millimeters just as you cut it resulting in the stressed plastic on the opposite gates of the part. Regardless how far from the part you cut the gate the thinnest plastic connection on the opposite gates will become stressed. How do you solve this? By cutting out the part starting from the gate which is going to be the most visible on the model, so the rest stressed gates are in less significant places? Or finding the thinnest nippers available? Since any cutting blade thickness is obviously more than 0 millimeters it seems like it's impossible to cut it 100% clean.

    • @i.r.o.4456
      @i.r.o.4456  9 หลายเดือนก่อน

      That is indeed correct. As you mentioned, the visible nub marks are caused both due to stress applied to the gate while you’re cutting it and the blade not thin enough. Tools such as god hand helps a bit since unlike most clippers, it actually cuts the plastic rather than squeezing it.
      Which is why I sanded a lot in this video to sand the surface just enough to get rid of the visual stress mark left from cutting.
      Granted this video is few years old now, and there are other numerous efficient way I found that involves melting plastic and such. The 100% method is just paint over the plastic once the surface is smooth.
      So use this video only as a guidance, and hope you can find better ways than what I did here. Have a wonderful day!

      If you’re referring to the scratches on the surface, then yes. Unfortunately to polish the surface you will need to gradually increase the sanding grit to get a polished surface.
      If you’re referring to the whitened surface from sanding, then still yes where you will need to sand till 8000 or more grit to restore the plastic sheen. You can avoid going to extra step if you top coat the models

      Hobby knife is super effective at removing nub marks, but it does require some precision and control.
      Which is why I use sanding paper because it offers consistent clean result for removing nub marks. The procedure, however, tends to get extremely grinding when you have to do it for dozens of parts.
      The fastest and easiest way would be to use a hobby knife to get a flat surface, and painting over that surface.

      @@i.r.o.4456 hey so I just did a test w 400 and 1000, after the 1000 I used the balancer that I mentioned and it works. It has 2 sides of them so I used the side to polish it and it looks great 👍

    does 3000 achieve the same glossy finish?

      In my experience it looks like it, but you can definitely try and see for yourself

    Do I just skip doing this and top coat or do I still have to sand it still? (First timer, built a Deathscythe the other day)

      After years later, you can skip most of the step and just top coat the model. Hope that helps!
