KLEAN-STRIP Aircraft Ultra Paint Remover — Quart
The Aircraft Ultra Aqua-Lift formula is designed to detach coatings quickly while offering visible progress. It targets tough automotive finishes by softening paints to bare metal in 30 minutes or less, which can dramatically shorten workshop timelines. The product spans multiple substrates, including metal, fiberglass, and certain plastics, making it a versatile choice for mixed-material restorations. Use with adequate ventilation and PPE to minimize exposure to fumes and skin contact.
- Fast-acting formula with patent-pending strength
- Visible lifting confirms coating removal progress
- Effective on 2K automotive coatings, epoxies, and urethanes
KLEAN-STRIP Aircraft Ultra Paint Remover — Aerosol 15 oz
This aerosol version mirrors the Quart’s capabilities in a convenient spray format. Ideal for spot treating edges, corners, or small parts, the aerosol allows controlled application and rapid coverage with minimal drips. Its chemistry is designed to lift coatings visibly and strip 2K automotive finishes efficiently while remaining compatible with metal, fiberglass, and flexible plastics.
- Portability for small areas and touch-ups
- Rapid strip of epoxies and urethanes
- Compatible with multiple automotive substrates
Citristrip Paint & Varnish Stripping Gel — 1 Quart
The Citristrip gel uses a citrus-based formulation with a pleasant scent, designed to cling to vertical surfaces and remain active for a meaningful duration. The gel’s viscosity helps minimize run-off on complex automotive body panels, improving residue control during batch stripping. It is suitable for a range of coatings, including varnishes, lacquers, and some enamels, making it useful for pre-paint prep and restoration workflows.
- Citrus-scented, user-friendly formula
- Clings to vertical surfaces for extended contact
- Effective on multiple traditional finishes
KLEAN-STRIP Aircraft Paint Remover (15 oz Aerosol)
This professional-grade aerosol is designed for faster stripping of tough automotive coatings while ensuring broad substrate compatibility. It tackles polyurethane and epoxy finishes with a practical application profile, including clinging to vertical surfaces to minimize drips. The aerosol format makes it well-suited for workshops where controlled application on panels or assemblies is needed.
- Fast acting on 2K automotive coatings
- Versatile on metal, aluminum, and many plastics
- Professional-grade performance for automotive and DIY use
Citristrip Gel QCG73801T — 1 Quart
Goof Off Citristrip Gel offers a better-smelling, heavy-duty option for multiple layer stripping outdoors or indoors. The gel’s vertical-surface cling and 24-hour active window support progressive coating removal across several cycles if needed. It’s designed to stay wet, enabling efficient stripping of older, thicker finishes while minimizing odor and splash compared to solvent-heavy alternatives.
- Sticky gel for vertical surfaces
- Active up to 24 hours for multi-layer stripping
- Industrial-strength performance with citrus scent
Buying Guide: Key Purchase Considerations
- Coating type and thickness: For epoxies, urethanes, and baked enamels, choose a formula with proven efficacy on 2K automotive coatings and baked finishes. Gel formulas are often best for vertical panels, while aerosols excel on small parts and edges.
- Surface compatibility: Ensure the product is suitable for metal, fiberglass, and the plastics found in automotive assemblies. Test on a hidden area first to gauge any discoloration or surface attack.
- Application environment: If you work in a closed shop, prioritize low-odor or low-VOC options, and ensure adequate ventilation and PPE. Non-flammable formulas help reduce fire risk in busy bays.
- Residual cleanup: Look for products that leave little to no residue after washing or wiping. Clean-up efficiency saves time during prep and repaint cycles.
- Safety and PPE: Use chemical-resistant gloves, goggles, and protective clothing. Some formulas may require solvent-compatible skin protection due to prolonged exposure potential.
- Ventilation and safety data: Review Safety Data Sheets (SDS) for ventilation requirements, exposure limits, and first-aid measures, especially for concentrated aerosol products.
- Cost and coverage: Consider yield per can or quart and calculate project scope. Aerosols are convenient for spot work; liquids cover larger areas economically.
- Environmental considerations: Some Citristrip products emphasize low odor and user-friendly disposal, but always follow local regulations for disposal of spent strippers and rags.
- Storage and handling: Keep containers sealed, away from heat sources, and out of reach of children. Label all containers clearly in the workshop.
