<h3>Dicor: Four Decades of RV Industry Innovation</h3><p>Since 1984, Dicor Products has established itself as a premier supplier of component products for the recreational vehicle industry. What began as a focused mission to deliver exceptional roofing solutions has evolved into a comprehensive portfolio of specialty products that help RV manufacturers and owners maintain, protect, and enhance their vehicles. The brand's expertise stems from decades of hands-on experience not just in supplying components, but in engineering and building RVs themselves—a unique perspective that informs every product they develop.</p><h3>Roofing Excellence and Protective Solutions</h3><p>Dicor's reputation rests primarily on its premium RV roofing systems and maintenance products. The company pioneered EPDM rubber roofing technology for recreational vehicles, creating durable membranes that withstand the demanding conditions RVs face—from intense UV exposure to temperature extremes and constant road vibration. Their roofing systems feature a three-part approach: high-quality rubber membranes, specialized lap sealants that create watertight seals around roof edges and penetrations, and protective coatings that extend roof life while maintaining flexibility.</p><p>The brand's <a href="/19328-vinyl-sealant-repair-kit-dicor-7315">vinyl sealant repair kits</a> exemplify their commitment to the aftermarket, providing RV owners with professional-grade solutions for maintaining and repairing rubber roofs between professional services. These products use the same elastomeric technology found in OEM applications, ensuring repairs blend seamlessly with existing roof systems while delivering long-lasting protection against moisture intrusion.</p><h3>Engineering Support and Customer Partnership</h3><p>What distinguishes Dicor in a competitive marketplace is their value-added engineering approach. The company provides on-site technical support to manufacturing partners, helping optimize installation processes and product application techniques. This consultative relationship has fostered deep, long-standing partnerships with major RV manufacturers who rely on Dicor's expertise to improve production efficiency while enhancing end-product quality. Their team actively seeks innovative solutions for the unique challenges RV construction presents, from weight considerations to thermal expansion issues.</p><h3>Beyond Roofing: Diversified Product Portfolio</h3><p>While roofing products remain their flagship offering, Dicor has expanded into complementary categories that leverage their materials science expertise. The brand's Versa Liner wheel cover line has achieved remarkable success, with over one million sets in service across North America. These covers protect RV wheels from road debris and weather while enhancing aesthetic appeal. Dicor also manufactures specialty sealants for windows, doors, and compartments, along with care products like rubber roof cleaners and conditioners formulated specifically for EPDM surfaces.</p><h3>Commitment to Quality and Innovation</h3><p>Dicor maintains rigorous quality standards across their product lines, backed by extensive testing protocols that simulate years of real-world exposure. Their continuous product development efforts focus on addressing evolving industry needs—whether that means formulating low-VOC sealants for environmental compliance or engineering faster-curing products that accelerate manufacturing throughput. As part of the Airxcel family of brands, Dicor benefits from broader resources while maintaining the specialized focus that has made them an industry leader. For RV owners and manufacturers alike, Dicor represents reliability, technical excellence, and products engineered to perform under the most demanding conditions.</p>

This is my 4th autoplicity purchase. I love you guys!!

So far easy to order

Fast, lowest price and in stock battery.

Just recieved my order and the pit jug and spout were perfect. The shipping was very fast and it was by far the best price I could get on these products. Autoplicity is great.

Fast

Website is easy to navigate. Parts are easy to find. Checkout was very simple to use. Good overall service.

Cheapest price by far, not the speediest shipment unfortunately.

this is supposed to fit my 2003 Chevy avalanche 4 x 4 Z71 with cladding correct?

I ordered parts expecting my in stock items to be delivered promptly. Had a few issues there. The logistics need to be updated. I was contacted about the mistakes made and was justly compensated. I appreciate the second effort and will give them another try.

good

I would definitely recommend Autoplicity. I ordered Thule bike racks (THU-518), and the products arrived in 2 days in perfect condition. Plus the prices (along with free shipping) were the best on the web.

Best price for the optima battery I needed for my boat, I will definitely add this site to my favorites.

Best prices quick and easy site!!
