Every serious ceramic coating installation, paint correction sequence, and prep step before protection application reaches the same point: the surface needs to be chemically clean. Polishing oils, silicone residue, wax, and airborne contamination must be off the paint before a coating bonds to it, before a sealant locks in properly, before a PPF installer can guarantee adhesion. The standard professional tool for that final wipe is isopropyl alcohol — and the purity level matters.
99% IPA evaporates completely and leaves zero residue. Lower-purity versions (70% or 91%) contain water and other carriers that can leave a thin film behind — exactly what a ceramic installer cannot have on the panel. Isopropyl Alcohol 99% from Polishing Systems Inc is industrial-purity IPA supplied in a working-size container for professional shop use.
What 99% Isopropyl Alcohol Is
This is technical-grade isopropyl alcohol (2-propanol, CAS 67-63-0) at 99% purity with less than 1% water content. At this concentration, it evaporates fully from paint and glass within seconds, leaving a completely dry, oil-free, residue-free surface. It is the standard panel-wipe solvent used in paint correction shops, ceramic coating studios, and automotive body shops for surface prep.
Key Features and Why They Matter
- 99% purity — virtually no water content means no risk of water spots or surface film after evaporation. Essential for pre-coating panel wipes where residue of any kind is unacceptable.
- Fast complete evaporation — flashes off in seconds on a paint surface, leaving the substrate immediately ready for coating or sealant application without a wait period.
- Polishing oil reveal — a wipe down with IPA after machine polishing removes filler oils that can mask true paint correction results. This is how professional correctors verify their work before the customer sees it.
- Multi-surface compatibility — safe on cured automotive paint, glass, and most metal surfaces when used as directed. The standard prep solvent across detailing, body shop, and coating workflows.
Critical Safety — Read Before Use
Isopropyl Alcohol 99% is highly flammable (flash point 53°F / 12°C). Handle with appropriate precautions:
- Use only in well-ventilated areas, away from open flames, sparks, and heat sources
- Wear chemical-resistant gloves and eye protection
- Do not spray in aerosol form or near ignition sources
- Do not use on hot surfaces or in direct sunlight where flash-off vapors can accumulate
- Do not use on ABS plastics, polystyrene, or polycarbonate surfaces — IPA may craze or cloud these materials
- Store in approved flammable-storage containers away from heat
Who Uses 99% IPA
Ceramic coating installers performing panel wipes before every coating application. Paint correction specialists running IPA wipe-downs to reveal true correction results. Body shops prepping bare panels before primer. PPF installers cleaning substrates before film application. Any shop where a chemically clean, residue-free surface is required as a prep step.
How to Use
- Pour a small amount of IPA onto a clean, folded microfiber or lint-free wipe — do not saturate the wipe, use a light application.
- Wipe the panel in one direction using light, overlapping passes. Fold to a clean section frequently.
- Allow to flash evaporate fully (10-30 seconds, surface and temperature dependent).
- Inspect the panel under proper lighting. Any remaining oil or residue will be visible as a slight sheen.
- Repeat on any panels showing residue. Do not touch panels with bare hands after the IPA wipe — oils from skin contaminate the surface immediately.
- Dispose of IPA-soaked wipes in a closed metal waste container — they are a fire hazard if balled up or left exposed.
Why the 5-Gallon Size
For coating studios and correction shops doing 10+ vehicles per week, the 1-gallon container becomes a reorder burden. The 5-gallon pail cuts the cost-per-ounce of 99% IPA significantly and eliminates the logistical overhead of frequent small orders. Decant into working spray or squeeze bottles from the pail for day-to-day use — the pail stays sealed in the flammable storage cabinet until needed. For shops running even higher volume, the 15-gallon drum is available. Shops just starting ceramic or correction services can evaluate the 1-gallon size first.
Frequently Asked Questions
What is the difference between 99% and 91% or 70% IPA?
The percentage refers to IPA concentration versus water content. 70% IPA is 30% water — designed for medical disinfection where water content slows evaporation. 91% is better but still contains enough water to leave a surface film. 99% evaporates fully and leaves no residue, which is the requirement for coating prep work. Using lower-purity IPA for ceramic coating prep is a common error that can compromise coating adhesion.
Will 99% IPA damage automotive paint?
99% IPA used correctly as a panel-wipe prep step on cured automotive paint does not damage modern clear coats. It will remove wax, sealants, and polishing oils — which is the point. Do not allow it to pool or dwell on painted surfaces for extended periods, and avoid use on freshly painted panels before the clear coat has fully cured.
How do I safely dispense from a 5-gallon pail?
Use a hand-operated or electric drum pump rated for flammable solvents into an approved dispensing container. Static grounding between containers is required when transferring flammable liquids. Work in a well-ventilated area and follow all flammable liquid handling protocols. IPA vapor is heavier than air and can accumulate at floor level — never transfer near floor drains or pits.
Can this ship by ground?
Yes — 5-gallon IPA ships by ground freight under standard hazmat protocols for flammable liquids. Cannot ship by air. Hazmat documentation is handled on every order.
What other sizes is 99% IPA available in?
Also available in a 1-gallon working container for lower-volume operations and a 15-gallon drum for high-throughput shops.
