SEM Vinyl Prep Cleaner Spray 13.3 oz Aerosol — removes grease & wax for better paint adhesion

SEM SEM38343 Vinyl Prep is a fast-acting 13.3 oz aerosol cleaner that removes dirt, wax and grease while conditioning vinyl for better topcoat adhesion.

This aerosol is formulated for paint and body work where clean vinyl substrates are required before applying coatings. It dissolves road grime, residues and oily films that can interfere with primer or paint bonds, leaving the surface ready for the next step. The compact 13.3 oz can makes it convenient for shop benches, mobile detailers or DIY projects where precise, controlled application matters.

How does this spray improve paint and body preparation?

SEM SEM38343 eliminates common contaminants that prevent coatings from sticking properly. By softening and removing soils and residual waxes, it creates a cleaner molecular surface for primers and paints to adhere to, reducing the risk of lifting or uneven coverage.

• Removes grease, wax and road film that interfere with adhesion
• Softens contaminants for easier wiping and less abrasion
• Designed for compatibility with vinyl substrates before topcoating
• Aerosol delivery allows targeted application in tight spots and seams

When should I reach for this product during my workflow?

Use the SEM38343 aerosol after initial cleaning and before any priming, painting or vinyl repair. It’s ideal as the final wipe-down step to ensure the surface is free of residues that could contaminate coatings applied immediately afterward.

• Final cleaning step prior to primer or paint
• Between sanding and painting to remove dust and oils
• Before adhesive or patching work on vinyl substrates
• Useful during touch-ups where localized cleaning is required

Is the aerosol easy to use and suitable for shops or mobile work?

Yes — the 13.3 oz aerosol is designed for practical, controlled spraying without need for separate mixing or equipment. Its portability and spray pattern make it convenient for both professional body shops and mobile technicians who need a reliable prep cleaner on-the-go.

• No mixing — ready-to-use aerosol format
• Compact can size fits toolboxes and work carts
• Controlled spray reduces overspray and waste
• Works well in bench, bay, or field environments

What surfaces and limitations should I be aware of?

This product is formulated for vinyl substrates and the surrounding areas involved in paint and body operations. Avoid use on surfaces that may be affected by solvents (test an inconspicuous area first) and do not treat finished interior trim where prolonged exposure to solvent vapors could alter texture or color.

• Specifically tuned for vinyl and related substrates
• Test on painted or delicate surfaces before widespread use
• Not intended as a heavy-duty degreaser for engine parts
• Follow safety and ventilation recommendations on the can
