Why RV Exterior Corner Molding Is Necessary
From my experience, RV exterior corner molding is essential for both protection and aesthetics. The corners of an RV are especially vulnerable to damage from road debris, weather, and everyday wear and tear. Without this molding, the edges can easily chip, crack, or peel, leading to costly repairs down the line. The molding acts as a sturdy shield that absorbs impacts and prevents moisture from seeping into the seams, which helps avoid water damage and rust.
I’ve also found that corner molding gives my RV a polished, finished look. It covers up rough edges and uneven joints, making the whole exterior appear cleaner and more streamlined. Plus, since it’s designed to be weather-resistant, it holds up well against sun exposure and rain, maintaining my RV’s curb appeal over time. For me, installing or replacing corner molding is a small investment that pays off by keeping my RV protected and looking great for many trips to come.
My Buying Guides on Rv Exterior Corner Molding
When I first started looking for RV exterior corner molding, I quickly realized how important this small component is for both the look and protection of my RV. Over time, I’ve learned a few key things that helped me choose the right molding to keep my rig looking great and shielded from the elements. Here’s what I want to share with you from my experience.
Understanding What RV Exterior Corner Molding Is
To start, it’s helpful to know exactly what corner molding does. It’s a trim piece that covers and protects the vertical edges of your RV’s exterior panels. It helps seal gaps, prevent water infiltration, and provides a finished look to the corners. Without it, your RV’s edges could get damaged or let moisture inside, leading to bigger problems down the road.
Material Matters: Choosing the Right Type
One of the first things I checked was the material. Most corner moldings come in aluminum, plastic, or rubberized vinyl.
- Aluminum: Durable and resistant to weather, but can dent if hit. It also looks sleek and often matches other exterior trim.
- Plastic: Lightweight and affordable, but may become brittle in cold weather over time.
- Vinyl/Rubber: Flexible and good at sealing gaps, but may fade or crack under harsh sun exposure.
For my RV, I opted for aluminum because I wanted durability and a clean finish, but if you’re on a budget or want easier installation, plastic or vinyl could work well.
Size and Fit Are Crucial
I learned that corner moldings come in different sizes and profiles to fit various RV models. Measuring your existing corner molding or the corner edges carefully is key. I took precise measurements of the height and width of the corner to find a matching molding that would fit snugly without gaps. Some moldings are universal, but I found that a model-specific or closely matching size gave the best results.
Installation Process and Ease
I also considered how easy it would be to install. Some moldings require screws or rivets, while others use adhesive backing. If you’re not comfortable with tools, look for self-adhesive options or ones that come with clear instructions. I personally used a molding that needed a few rivets, but I had the tools and experience to handle it. Also, keep in mind that proper surface cleaning before installation is essential to ensure good adhesion.
Weather Resistance and Durability
Since the molding is exposed to sun, rain, wind, and road debris, I checked for weather resistance. UV protection and rust-resistant coatings can extend the life of the molding. My aluminum molding had a powder-coated finish, which really helped maintain its look after many months on the road. If you live in an area with extreme weather, prioritize moldings with proven durability.
Matching Your RV’s Exterior Style
Although function is the priority, I also wanted the molding to complement my RV’s design. Moldings come in different colors and finishes—white, black, silver, or even beige. Matching or contrasting the molding to your RV’s exterior paint or decals can enhance the overall appearance. I chose silver aluminum since it matched other trim pieces on my RV.
Budget Considerations
Finally, I balanced quality with price. While some high-end moldings cost more, they can save you money in the long run by lasting longer and protecting your RV better. Cheaper options might be tempting but could require replacement sooner. I set a reasonable budget and found a good quality molding that fit it without sacrificing durability.
Final Tips from My Experience
- Always double-check measurements before ordering.
- Clean the surface thoroughly before installation.
- Consider ordering a little extra length in case you need to trim for a perfect fit.
- If unsure, consult your RV manufacturer or a specialist to get recommended molding types.
Choosing the right RV exterior corner molding made a noticeable difference in protecting my rig and keeping it looking sharp. I hope these tips help you find the perfect fit for your RV too!
