Crack resistant and suitable for interior and exterior use, it’s a top-rated prep essential for flawless vinyl paint finishes. ## Description Sand Free is a unique wet-on-wet adhesion promoter for certain plastics. It softens the substrate promoting adhesion on difficult to sand areas. Review: A Must Prior to Vinyl Paint - Great preparation product to apply prior to vinyl paint. It really helped with paint adhesion. Review: Seems to work as advertised - After calling SEM and getting some very helpful information from a nice gentleman, this was a simple job. I'm changing the color of the interior of my classic car, and I started with the console. After you spray the Sand Free, you have 30 seconds to lay down the first coat of paint. (The paint was also SEM for hard plastic). Apply 2-3 coats. I reassembled the console, and it looks great! Hopefully it will stand the test of time, as far as scratching or peeling...fingers crossed. ## Features - Sand Free is a unique wet-on-wet adhesion promoter for certain plastics - It softens the substrate promoting adhesion on difficult to sand areas ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00B3HXM6I | | Best Sellers Rank | #154,021 in Automotive ( See Top 100 in Automotive ) #133 in Automotive Spray Paint | | Brand | SEM | | Brand Name | SEM | | Color | Clear | | Compatible Material | Plastic | | Container Type | Can | | Customer Reviews | 4.7 out of 5 stars 157 Reviews | | Global Trade Identification Number | 00646786383632 | | Included Components | SEM 38363 Sand Free - 11.6 oz | | Item Form | Aerosol | | Item Package Quantity | 1 | | Item Type Name | SEM 38363 Sand Free - 11.6 oz | | Item Weight | 0.5 Pounds | | Manufacturer | SEM | | Model | 38363 | | Other Special Features of the Product | Crack Resistant | | Part Number | 38363 | | Special Feature | Crack Resistant | | Specific Uses For Product | Interior/Exterior | | UPC | 646786383632 | | Unit Count | 11.6 Ounce | | Volume | 11.6 Fluid Ounces | | Warranty Description | Warranty | ## Images ![SEM 38363 Sand Free - 11.6 oz - Image 1](https://m.media-amazon.com/images/I/815v6N14zFL.jpg) ## Questions & Answers **Q: Will this work with water based primers for exterior auto body parts?** A: I would not use this with a primer, It is designed to "melt" the color coat into hard plastics and takes the place of primer for paint adhesion **Q: Can Sand Free be used on plastic chrome I want black out or will it soften and wrinkle the chrome coating?** A: You need to use SEM sku# 39863 if you are using an adhesion promoter. Sand Free is probably to agressive for the plastic chrome **Q: Will this work for the textured Sail panels for my Avalanche?** A: I used it on the fenders/trim on a jeep wrangler and it worked very well. To answer your question it depends on exactly what kind if plastic you want to paint. SEM has a good website. Look up what plastic your sail panels are made from and see if SEM lists it as one that this works on. Just make sure to paint it while it is still wet with this solvent. **Q: What is the difference between this and their other plastic adhesion promoters?** A: I haven't used mine yet, however, it is recommended in this paint system and I have seen the results when the instructions are followed as directed by the manufacturer. I am not going to risk using anything else. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A Must Prior to Vinyl Paint *by N***E on June 28, 2025* Great preparation product to apply prior to vinyl paint.
