BOSSDE P-161 1K Grey Automotive Primer Fast Dry Easy Sanding for Polyester Putty Spot Repair
Start with the product specification your buyers need
BOSSDE P-161 is a grey, single-component primer intended to fill fine coating-surface defects and improve adhesion between coating layers. Its named substrates are unsaturated polyester putty and sanded existing paintwork.
For a refinish distributor or purchasing team, these details define the offer more accurately than a broad “universal primer” label. P-161 has a nitrocellulose-containing formulation, a stated primer-to-thinner ratio of 100:80–100 and fast-drying, easy-sanding product characteristics. The measuring basis and complete spray instructions should accompany qualification of the product.

Select the purchase format first
| Listed format | Information for the enquiry |
| 3.75 L | Required quantity, intended sales unit and confirmed outer packing |
| 20 L | Required quantity, handling arrangements and separate packing details |
The source also lists an outer carton of 4 cans, 34.5 × 34.5 × 20.7 cm. It does not explicitly map this carton to a pack size in the extracted text. Have the supplier confirm the association before calculating carton counts or freight.
Container material, shipping weight, pallet loading and current availability are quotation details. Do not infer these values from nominal litres.
Where this primer fits in a trade range
Refinishing suppliers serving bodyshops
Offer P-161 for the stated fine-defect preparation role over qualifying substrates. Supply the thinner recommendation and mixing instructions with the primer so buyers receive a usable system specification rather than only a can size and price.
Multi-site repair businesses setting purchasing standards
Use the exact model, document revision and packing specification in the approved-material list. Each shop still needs the correct preparation and application process; common purchasing does not establish identical drying conditions everywhere.
Parts-refinishing accounts with suitable retained paint
The source's directory mentions small automotive-part coating work. For such an enquiry, qualify the actual substrate first. The verified substrate statement covers polyester putty and sanded existing paint, not unrestricted coating of bare metal or bare plastic components.
These are representative buyer situations, not documented installations or customer endorsements.
Why buyers consider P-161
A clear place in the coating sequence. Its purpose is surface refinement and intercoat adhesion over named prepared substrates. This supports an accurate technical sales description.
A choice of two listed volumes. The 3.75 L and 20 L formats let buyers discuss different supply arrangements while keeping the same product identity. Confirm actual packing and commercial terms for each format.
A fine film designed for sanding. Easy sanding and fast drying are stated features. They are qualitative product descriptions, not measured comparisons with competing primers.
A specified reduction range. The source provides 100 parts primer to 80–100 parts thinner. This offers a concrete starting instruction, subject to confirmation of the measurement basis, thinner and application conditions.
A documented unopened storage reference. The product information states 24 months at 20°C in the original sealed container. That condition should remain attached to any shelf-life claim.
Understand the formulation and process role
The listed ingredients are nitrocellulose, specially modified resins, pigments, fillers, additives and organic solvents. P-161 is described as a 1K grey primer; the application mix lists thinner without a hardener component.
The primer is positioned after the appropriate substrate preparation and before the approved subsequent coatings. The exact solvent composition, physical properties and transport information require the current SDS. A broad ingredient list is not a substitute for those documents.
Compare roles before proposing a substitution
| Buyer request | How to assess P-161 |
| “We need a primer after preparing polyester putty.” | This is within the named substrate direction; confirm the full coating sequence. |
| “We need to refine sanded existing paint.” | Check the retained coating's condition and system compatibility. |
| “We need a replacement for our specified 2K surfacer.” | Do not assume equivalence; compare the actual process requirements and technical data. |
| “We need a bare-metal protective primer.” | No direct-to-metal or corrosion-protection approval is established here. |
| “We need adhesion to bare plastic.” | This use is not supported by the verified substrate list. |
No comparative filling depth, adhesion rating, sanding-time saving or corrosion result was supplied in the extracted information.

How to qualify P-161 for repeat supply
Write a representative application brief
Identify whether customers will apply the primer over polyester putty or existing paint. Record the preparation method and subsequent coating products. Seek approval for the proposed combination before a production trial.
Resolve the mixing details
Confirm the thinner model and whether 100:80–100 is measured by volume or weight. Record the selected ratio within the approved guidance. Do not replace the specified thinner with another product simply because both are sold for automotive paint.
Run the complete preparation and finishing process
Use the current viscosity, equipment, coat-count and film-thickness instructions. Assess sanding only after the specified drying conditions have been met. Evaluate the finished coating sequence, rather than judging the primer solely by its appearance immediately after spraying.
Retain a repeatable record
Keep product and batch identity, technical document revision, thinner, measurement basis, conditions and observations with the trial record. Agree acceptance criteria before making claims about comparative performance.
Documentation for procurement review
The supplier's source states “no heavy metals” and compliance with EU RoHS requirements. Treat these as supplier declarations until the applicable reports and scope have been reviewed. The extracted information does not provide a test report, certificate number or independent verification.
Ask for the current TDS, SDS, applicable declaration and supporting analytical evidence if these statements affect the purchase. Do not relabel the product “EU certified,” “non-toxic” or approved for an unrelated application on the strength of this wording.
Storage and stock handling
The 24-month statement applies at 20°C with the original closure intact. It does not establish a new storage period after opening or after repacking.
The source instructs users to keep the product tightly closed in a cool place, protected from water, leakage, sunlight and high temperature, and away from ignition sources. Prompt closure after dispensing helps avoid the surface skinning described in the source. Use the SDS for complete handling and transport requirements.
Wholesale and custom-brand projects
Build the wholesale enquiry around pack size, order quantity, destination and forecast repeat demand. Request an offer identifying carton configuration, shipping weights, delivery terms and the recommended thinner.
If the project requires OEM branding, provide the proposed brand, label language, packaging brief and volume forecast. Private-label supply and packaging changes are not confirmed for P-161 in the available information. Agree capability, artwork responsibility, minimum quantities and lead time before advertising customisation.
