Ceramic coating installers, PPF studios, and body shop prep technicians have one thing in common: they use paint prep spray every day on every vehicle. The pre-coating wipe, the pre-paint silicone check, the post-correction oil removal — paint prep product is not a once-in-a-while specialty use. It is a routine consumable that needs to be consistently available at a cost that makes sense for regular professional use.
Duz-All Clear Coat Cleaner 1 Gallon (SKU P-40) is the professional supply format of this purpose-formulated automotive paint prep solution. The 1-gallon jug fills multiple working spray bottles, keeps supply available throughout the week without mid-job restocking, and delivers a meaningfully lower per-ounce cost than the 16-oz spray size. For coating installers doing 3+ vehicles per week, the gallon is the practical working format.
What This Product Is
This is Duz-All’s automotive paint prep and clear coat cleaner in 1-gallon working volume. The same formula available in the 16-oz spray — formulated to remove polishing oils, silicone, wax residue, and surface contamination from clear coat before coating, film, or protection application — supplied in bulk format for decanting into spray bottles. Leaves paint surfaces clean and oil-free for proper product adhesion.
Key Features and Why They Matter
- 1-gallon production volume — fills 4–8 standard 16-oz spray bottles depending on fill level. Keeps multiple working spray bottles stocked across a production coating studio without constant restocking.
- Lower per-ounce cost — the 1-gallon size delivers a significantly better unit economics versus the 16-oz size for operations using the product regularly.
- Professional-grade paint prep formula — strips the contamination types that affect coating adhesion: polishing oils, silicone from spray detailers and panel wipes, wax residue, and general surface product buildup.
- Clear coat safe — removes surface contamination without hazarding the clear coat underneath. Proper prep chemistry that works with rather than against the coating installation process.
What This Is NOT For
Not a paint correction product — it removes contamination, not defects. Not a substitute for proper washing and clay decontamination before prep. Not appropriate for use on matte, satin, or specialty clear coats without testing. Do not allow to dry on the surface — wipe and buff clean while the product is wet. Not for interior use on leather, vinyl, or fabric surfaces.
Who Uses This
Ceramic coating studios doing 5+ installations per week use the gallon format as their standard supply — coating application workflows require a prep wipe on every panel before coating goes down, making this a high-consumption item at production volume. Body shop prep technicians use a gallon to supply the panel wipe stations in a busy spray booth prep area. Mobile detailers running multiple ceramic coating or full detail services per week find the gallon economical versus restocking individual spray bottles. Compare to the 16-oz spray size for individual detailers or lower-volume operations where the smaller format is more practical.

How to Use
- Decant: Pour into clean spray bottles — use solvent-compatible HDPE or glass spray bottles rather than generic household spray bottles.
- Apply panel by panel: Spray onto a clean microfiber wipe towel or directly onto the panel section being prepped.
- Wipe: Straight overlapping passes across the panel with a clean microfiber. Fold frequently to expose clean towel sections.
- Buff dry: Immediately follow with the dry side of the microfiber to fully remove product before it dries on the surface.
- Coat or protect: Apply ceramic coating, sealant, or PPF immediately after prep to avoid re-contamination.
Frequently Asked Questions
How many spray bottles does 1 gallon fill?
One gallon (128 oz) fills approximately four 32-oz spray bottles or eight 16-oz spray bottles. For a ceramic coating studio doing multiple vehicles per day, this provides enough working supply for several days of continuous use depending on vehicle size and number of panels prepped.
Is this product the same formula as the 16-oz spray?
Yes — the 16-oz and 1-gallon sizes contain the same Duz-All Clear Coat Cleaner formula. The gallon is simply the bulk supply format at lower per-ounce cost, not a different concentration or formulation.
Do I need to dilute this product before use?
Duz-All Clear Coat Cleaner is used ready-to-use — no dilution required. Decant into a spray bottle and use as-is. Diluting the product would reduce its effectiveness for contamination removal, which is counterproductive for the pre-coating prep step where complete surface decontamination is the objective.
After using Duz-All, how soon should I apply the ceramic coating?
Apply coating as soon as possible after the prep wipe — ideally within minutes — before the clean panel is re-contaminated from handling, air exposure, or product drift in the shop environment. Most coating installation protocols prep one panel and coat it immediately before moving to the next panel, rather than prepping the entire vehicle and then coating.
How long does an opened gallon stay effective?
Stored properly — in its original sealed container in a cool, ventilated location — opened Duz-All Clear Coat Cleaner retains full effectiveness for an extended working period. Decant into spray bottles as needed and keep the gallon jug sealed between uses to minimize evaporation and contamination of the bulk supply.
