مرونة عالية من A.O. بسماكة 3/16 بوصة مقاس 4 1/2 بوصة × 5 1/2 بوصة (وجه واحد)

This sheet cuts through heavy rust on my trailer hitch without shredding, and the 3/16" padding lets me apply real pressure. I’ve been using the same piece for three hours of detail work on metal.

I was skeptical about a single-sided flex sheet holding up, but this one’s 3/16” thickness keeps it rigid enough for detailed work without tearing. Used it on a curved metal surface and it followed the contour perfectly.

I was skeptical about the 3/16" thickness being too stiff, but it actually bends nicely around curved surfaces without cracking. The high-flex side grabs well and lasts through several heavy-duty sanding jobs.
