Blaster ProStraw Rust Penetrant & Lubricant Spray 11 oz — Pack of 12, Dual-Pattern Nozzle & Adjustable Flow

B'laster 16-PB-DS ProStraw is a fast-acting rust penetrating catalyst and lasting lubricant designed to free frozen bolts, hinges and fittings while protecting metal from renewed corrosion.

When rust or weathering locks parts in place, you need a dependable spray that both penetrates seized connections and leaves behind a non-evaporating lubricant to reduce wear and future corrosion. This 11 oz aerosol comes with B'laster's patented ProStraw, a dual-pattern nozzle and volume adjuster that lets you switch between a focused stream for deep penetration and a wider spray for coverage. The pack of 12 is aimed at professionals and heavy users who service automotive, industrial, marine and plumbing equipment.

How does the ProStraw design help reach tight or rusted parts?

The ProStraw includes a dual-spray pattern and an adjustable flow control so you can tailor application to the job. Use the narrow, high-pressure stream to drive the penetrant deep into threads and seams, or flip to the broader spray for surface wetting and protection.

• Dual-spray pattern for pinpoint or wide coverage
• Volume adjuster allows measured application and less overspray
• Long straw reaches into crevices, behind fittings, and into bolt heads
• Quick-switch action for one-handed operation

What kinds of problems does it solve on vehicles, boats and machinery?

B'laster 16-PB-DS breaks corrosion bonds and frees frozen fasteners, valves and linkages while leaving a protective film that resists evaporation. It’s formulated to work on a range of metals and assemblies commonly affected by rust and saltwater exposure.

• Penetrates seized bolts, nuts, and threaded connections
• Loosens stuck hinges, locks, and small mechanical linkages
• Protects metal surfaces from further oxidation after treatment
• Suitable for vehicle underbodies, marine hardware, industrial machinery, and household plumbing

How should I apply it for best results and safety?

For fast results, apply the narrow stream directly to the rusted joint and let it soak a few minutes, then work the part. For broader protection, use the spray setting to coat exposed metal and moving parts. Always use in a well-ventilated area and follow label directions for PPE and disposal.

• Use precision stream for penetration; allow dwell time before attempting to move parts
• Apply wider spray for protective film on fittings and linkages
• Wear gloves and eye protection; avoid open flames and ignition sources
• Store upright in a cool, dry place away from heat

Why choose this pack size and who benefits most from buying a 12-pack?

Buying the 11 oz cans in a 12-pack provides consistent supply for commercial shops, fleet maintenance, marinas and serious DIYers who tackle frequent rust-related repairs. It reduces downtime and ensures you have enough product for repeated applications without running out mid-job.

• Bulk quantity lowers per-can cost and reduces reordering frequency
• Consistent product on-site for multiple technicians or projects
• Convenient for seasonal maintenance or large restoration jobs
• Packaged for commercial or heavy personal use with durable cans and ProStraw nozzles

Who is this for? If you maintain cars, trucks, boats, industrial equipment, or plumbing systems and regularly face corroded fasteners or sticky mechanisms, the B'laster 16-PB-DS ProStraw is built for you. It’s especially useful for mechanics, fleet managers, marine technicians, maintenance professionals and dedicated DIYers who need a reliable penetrant that also leaves protective lubrication. Avoid using it where manufacturer instructions prohibit lubricants, and refer to safety information on the can for proper handling.
