m*a様 3M Chrome Masking Tape 851A 19mm x 66m 851A

This is a very high-quality masking tape. While it might not be commonly used by the general public, it's incredibly versatile. My father used it, and now that he no longer needs it, I'm offering it here. It's quite expensive to buy new, so I hope someone can make good use of it.
It has been used a little, but please consider it if you're interested.

1. DIY and Model Making (Plating and Painting)
When using kits like Mekki Koubou (Plating Studio) at home for partial gold plating, this tape is perfect for protecting areas you don't want to plate, just as it's intended.
Benefits: Unlike regular paper masking tape (protective tape), it's resistant to liquid penetration, resulting in very sharp lines.

2. Protection for Areas Involving Water or Chemicals
Its high chemical resistance makes it suitable for protecting areas where strong cleaning agents are used.
How to use: Temporarily cover metal parts (like the base of faucets) or rubber seals that you don't want to come into contact with mold removers or acidic cleaners.
Benefits: The adhesive is applied thickly, allowing it to conform to slight unevenness and prevent chemicals from seeping in.

3. Repair and Insulation Protection for Electronic Devices
As it's designed for circuit boards, it's useful for insulation and heat protection for electronics enthusiasts.
How to use: Use as insulation to prevent short circuits when working on circuit boards inside computers or home appliances.
Benefits: The adhesive remains less sticky even when heated and peels off cleanly.

4. Temporary Fixing on Glass or Metal (Areas where you don't want to leave marks)
Made from a polyester base that resists stretching, it's ideal for areas that require secure fixing.
How to use: Attach notes or temporarily fix parts to glass, mirrors, or stainless steel products.
Benefits: Even when left on for extended periods, it leaves significantly less adhesive residue (stickiness) compared to general-purpose tapes.
