FR-90 is an advanced penetrating oil that shocks rust down to -40˚C, creating micro-cracks, allowing the lubricants to penetrate faster for rapid fastener removal. The silicone free formula is safe for use on all metals surfaces without staining and most plastic, paint and rubber coatings

Lubricant rapidly penetrates rust
Freeze shocks rust down to -40˚C, cracking surface rust (dependent on starting ambient temperature)
Creates micro-fissures in rust
Fitted with a 360˚ valve for all angle use
Suitable for use on all metal components
Does not contain silicone
