WOW! What a GREAT video. The title speaks for itself, and you nail it. Short, clear and concise, straight to the point. Probably the best "how to" sand/polish video I've found. Thank you for making this, I will definitely share it to a few faceytweets modeling GroNps, much appreciated!
Excellent video. I have a few 1:43 models and their plastic display cases have some minor scratches. Can you tell me please, if I should use only polishing compounds without using sandpaper first? Thank you.
Thanks for watching. It depends on how deep the scratches are. If deep, you need to sand with a grit that will remove the deepest marks, then progessively with finer grits until you finish with compounds.
Yes, 2000 grit is perfect for sanding paint before spraying another coat. It is fine enough to be covered by the fresh paint coat. If polishing the paint for high gloss, use 2000 then finer grades like 4000 and 10000 before rubbing with polishing compounds.
Yes, this is a technique that can be used to polish any plastic model surface and also painted surfaces. Hard painted surfaces work the best such as oil based enamel and solvent based lacquer paint.
As long as the lens is plastic this technique will work. Bare in mind that if the scratches are deep you will have distortion after polishing the lens.
I've also seen Tamiya polishing wax...when would you use that? is it for the same purpose here or is wax just meant to shine up any model whether polished or not?
The Tamiya wax is a coating applied after the model is finished, irrespective of polishing or not. It maintains a high gloss finish by repelling fine dust and debris. Make sure the model is completely finished before applying wax as no glue or paint will stick to the waxed surface.
@@HearnsHobbiesMelbourne - So the polishing compounds don't leave any coating, and or wax to mask any of the swirls or "fog"? In other words, is it purely a compound that smoothes the surface physically as opposed to filling in and masking the micro scratches (i.e. "fog")…?
Yes, gritty or rough paint finishes can be smoothed with sanding paper/sponges. Use at least 1000 grit or higher to avoid deep scratches. Spray your paint over the sanded area to finish.

Hello, there. Do you guys think this product will fix insecticide stain on plastic lenses of Oculus Quest 2? Will it be near factory condition if I apply your method correctly?

Thank you for watching and glad you enjoyed the presentation.
Really good guide for our beginners, thank you. I will use this way to polish my Tamiya Car model windows (NSX)
Glad it helped

Can the 2000 grit sandpaper be used to polish an already painted model?
Yes, 2000 grit is perfect for sanding paint before spraying another coat. It is fine enough to be covered by the fresh paint coat. If polishing the paint for high gloss, use 2000 then finer grades like 4000 and 10000 before rubbing with polishing compounds.
BJ Louey thanks 👍
Excellent tip. Can you use this technique to "shine" parts of a model too or is this generally for repairs?
Yes, this is a technique that can be used to polish any plastic model surface and also painted surfaces. Hard painted surfaces work the best such as oil based enamel and solvent based lacquer paint.
@@bjlouey6221 awesome, thanks BJ
Brilliant going as always from you
Thank you!
Can i use this technique on scratched projector lens ? I need to fix it , it's looks hazy and blury.
As long as the lens is plastic this technique will work. Bare in mind that if the scratches are deep you will have distortion after polishing the lens.
@@HearnsHobbiesMelbourne actually there are almost no scratches, but the surface is very matte therefore the image is very hazy.

I have just built a 1/48 Harrier and the airbrushed paint finish is very gritty. Will the tamiya sanding sponges sort that out?
Yes, gritty or rough paint finishes can be smoothed with sanding paper/sponges. Use at least 1000 grit or higher to avoid deep scratches. Spray your paint over the sanded area to finish.
Does that GSI polishing cloth have a product code or grade for ordering purposes?

Hello, there. Do you guys think this product will fix insecticide stain on plastic lenses of Oculus Quest 2? Will it be near factory condition if I apply your method correctly?
Hello. Sorry, I don't know how the stained lenses will cope with polishing. If the lenses have been optically coated then the coating will be removed.
Can demo that on a flat model?
The technique is the same on a flat model. Here is a different video ruclips.net/video/4LBRGKpQOto/видео.html
@@HearnsHobbiesMelbourne thanks 🙏🙏🙏

Of course duh. How are you going to remove the mark without sandpaper?
