A light scouring with a steel wool pad should be more than enough if the surface is already clean.<\/p>\n\n\n\n<p>Getting a surface ready for Por-15 requires more work than Rustoleum.<\/p>\n\n\n\n<p>It must be completely free of grease, oil, or wax, so you&#8217;ll want to start with Por-15 Marine Clean. Follow up with Metal Prep solution to eat through the rust and loosen the oxide layers on metal surfaces.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a>Recommended Application Temperature<\/h3>\n\n\n\n<p>Rustoleum Rust Converter is best applied at temperatures between 65\u00b0F (18\u00b0C) and 85\u00b0F (29\u00b0C), whereas Por-15 should be used when temperatures are between 50\u00b0F (10\u00b0C) and 75\u00b0F (24\u00b0C).<\/p>\n\n\n\n<p>Both products take up to 24 hours to dry, depending on the temperature and humidity of your workspace, so it&#8217;s a good idea to ensure you have enough time when you plan a project using either product.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a>Cost<\/h3>\n\n\n\n<p>Rustoleum is cheaper than Por-15, so it is your best bet if you&#8217;re on a budget.<\/p>\n\n\n\n<p>However, it&#8217;s important to note that Por-15 provides better results in the long run, while Rustoleum might require more frequent re-applications to sustain its effectiveness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a>Formulation<\/h3>\n\n\n\n<p>When it comes to Rustoleum vs. Por-15, the most significant difference is in their formulas.<\/p>\n\n\n\n<p>Rustoleum Rust Converter is a water-based latex coating formulated with phosphoric acid and <a href=\"https:\/\/www.sciencedirect.com\/topics\/materials-science\/chromate\" target=\"_blank\" rel=\"noreferrer noopener\">rust-inhibiting chromates<\/a>.<\/p>\n\n\n\n<p>When applied to rusted metal, it penetrates the rust and forms an iron phosphate surface layer that binds to the metal and provides a base for additional coats of paint.<\/p>\n\n\n\n<p>Por-15 contains <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S030094400100128X\" target=\"_blank\" rel=\"noreferrer noopener\">ethyl silicate<\/a>, which forms a flexible bonding film with metal surfaces and prevents oxygen from getting to the surface, effectively sealing out moisture and preventing further corrosion.<\/p>\n\n\n\n<p>It also contains rust-inhibiting pigments that remain effective even as paint coats wear off over time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a>Availability<\/h3>\n\n\n\n<p>Por-15 is a smaller brand than Rustoleum, and its products may be less widely available.&nbsp;<\/p>\n\n\n\n<p>You can find Rustoleum products at most hardware stores or home improvement centers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a>Results<\/h3>\n\n\n\n<p>When applied correctly, both products will form an extra layer between your surface and the outside world to protect against rust.<\/p>\n\n\n\n<p>However, if you choose Por-15, your protection will last longer than with Rustoleum.<\/p>\n\n\n\n<p>This product will effectively seal the surface against moisture and oxygen and provide UV protection, which is great if you live somewhere sunny or plan on leaving your newly treated surface exposed for long periods.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/mycarmakesnoise.com\/wp-content\/uploads\/2023\/03\/POR-15-vs.-Rustoleum-2-1024x682.jpg\" alt=\"POR 15 vs. Rustoleum\" class=\"wp-image-4397\" srcset=\"https:\/\/mycarmakesnoise.com\/wp-content\/uploads\/2023\/03\/POR-15-vs.-Rustoleum-2-1024x682.jpg 1024w, https:\/\/mycarmakesnoise.com\/wp-content\/uploads\/2023\/03\/POR-15-vs.-Rustoleum-2-300x200.jpg 300w, https:\/\/mycarmakesnoise.com\/wp-content\/uploads\/2023\/03\/POR-15-vs.-Rustoleum-2-768x512.jpg 768w, https:\/\/mycarmakesnoise.com\/wp-content\/uploads\/2023\/03\/POR-15-vs.-Rustoleum-2-1536x1024.jpg 1536w, https:\/\/mycarmakesnoise.com\/wp-content\/uploads\/2023\/03\/POR-15-vs.-Rustoleum-2.jpg 2000w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Can_You_Spray_Rustoleum_Over_POR15\"><\/span><a><\/a>Can You Spray Rustoleum Over POR15?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>While it is possible to spray Rustoleum over Por-15, it is generally not recommended.<\/p>\n\n\n\n<p>Both Por-15 and Rustoleum are designed to be self-priming and do not require an additional primer layer. Additionally, Por-15 creates a hard, non-porous surface that may not bond well with Rustoleum or other coatings.<\/p>\n\n\n\n<p>If you decide to apply Rustoleum over Por-15, you may need to lightly sand the Por-15 surface to create a rough surface that will allow the Rustoleum to bond correctly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Pros_and_Cons_Summary\"><\/span>Pros and Cons Summary<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>POR 15<\/strong><\/td><td><strong>Rustoleum<\/strong><\/td><\/tr><tr><td><strong>Pros<\/strong><\/td><td><strong>Cons<\/strong><\/td><td><strong>Pros<\/strong><\/td><td><strong>Cons<\/strong><\/td><\/tr><tr><td>Moisture strengthens the product instead of breaking it down<\/td><td>May have limited availability in your area<\/td><td>Dries very quickly<\/td><td>Not as tough against normal wear and tear<\/td><\/tr><tr><td>Forms a durable, non-porous surface<\/td><td>Does not adhere to smooth surfaces<\/td><td>Once dry, acts as a primer for new coats of paint<\/td><td>Requires surface preparation<\/td><\/tr><tr><td>Available in black, silver, gray, and clear<\/td><td>Requires a multistep process<\/td><td>Spray can is convenient for tackling small, quick repairs<\/td><td>Only available in black<\/td><\/tr><tr><td>Apply with a spray gun, brush, or roller<\/td><td>Prone to UV-damage without a top coat<\/td><td>Affordable<\/td><td>Prone to chipping and impact damage<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"So_Which_One_Is_Better_Overall\"><\/span><a><\/a>So, Which One Is Better Overall?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Ultimately, the choice between rust conversion products comes down to what&#8217;s best for you.<\/p>\n\n\n\n<p>Rustoleum is a decent product available almost everywhere and relatively affordable, while Por-15 offers a more robust, longer-lasting solution against rust. Both are excellent rust-prevention products and have a place in car maintenance and repair.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a>When to Use Por-15<\/h3>\n\n\n\n<p>Por-15 is the superior product for serious rust prevention jobs. It goes on thicker than Rustoleum and cures to a much harder layer.<\/p>\n\n\n\n<p>If you&#8217;re patching up larger holes in your car&#8217;s body or panels, Por-15 is the rust converter for you. It bonds tightly to the surface and won&#8217;t flake off as other products might. It&#8217;s perfect for larger areas, as you can brush or roll it on.<\/p>\n\n\n\n<p>It&#8217;s also ideal for use in extreme conditions\u2014think marine applications, working on vehicles exposed to road salt, or outdoor tools like lawnmowers and chainsaws.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a>When to Use Rustoleum<\/h3>\n\n\n\n<p>You should use Rustoleum if you don&#8217;t need rock-solid protection \u2014 say, if you&#8217;re doing minor rust repair and prevention on an indoor object like a table or chair.<\/p>\n\n\n\n<p>Its versatility and relatively easy application (no special tools required) mean that even beginners can achieve professional-looking results with minimal effort.<\/p>\n\n\n\n<p>Plus, it&#8217;s also helpful when your project involves repainting after fixing the rust, as it forms a primer-like layer that is ideal for paint.<\/p>\n\n\n\n<p>Rustoleum&#8217;s affordability makes it an excellent choice for DIYers who want to achieve high-quality results without spending too much.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Alternatives\"><\/span>Alternatives<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There are several alternatives to Por-15 and Rustoleum for preventing and treating rust on metal surfaces.<\/p>\n\n\n\n<p>Some popular options include:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a>Corroseal<\/h3>\n\n\n\n<p><a href=\"https:\/\/www.amazon.com\/Corroseal-Water-Based-Converter-Metal-Primer\/dp\/B07Y5XZJFX\" target=\"_blank\" rel=\"noreferrer noopener\">Corroseal<\/a> is a water-based rust converter similar to Rustoleum.
