Paint for the exterior (For Fiberglass)
Most RV will have a fiberglass exterior so we are going to focus on paints that are suitable for painting fiberglass.
It is important to get the right paint for the job. Using a standard all-purpose type of paint will not give you a good finish and it will probably end up costing you more in both time and money to put the job right.
Fiberglass paint comes in a wide range of colors and finishes including matt, gloss and high gloss which should allow you to get exactly the finish you are looking for.
It is always important to read the label on the container to make sure what you buy is right for the job. Look for paints that contain polyester, polyurethane, acrylic or epoxy. These will give you the best results for a tough and weather resistant finish.
Primer For Your RV
It is always a good idea to start with a primer. You might be tempted to skip this step to save time or money. But using a primer ensures that you get a smooth surface. That means that the main paint goes on nice and smoothly and dries evenly.
It is well worth that little bit of extra effort to ensure the best possible finish. And remember the better job you do now, the longer it will last saving you both time and money in the long run. . Primers based on epoxy, latex or urethane are recommended. If possible you should make sure to by the same brand of paint and primer.
Prepping the RV for painting

- Automotive sponge
- A palm sander
- Fine grit sandpaper

How To Paint RV Exterior Fiberglass
Pick A Good Place To Work!It is important to choose a good place to work such as a garage as long as it well ventilated, or your driveway as long as will be out of the sun.
Use Soap & An Automotive SpongePrepare the exterior for painting by giving the whole vehicle good clean using soap and an automotive sponge. Wipe down the exterior of the vehicle so that you remove all mess that has accumulated over the years of travel – You might find there is quite a buildup of dirt and grime and bird dropping especially on the roof.
Palmsander Using Wet SandpaperNext step is to use the palm sander to smooth down the exterior using wet sandpaper with a fine grit. No need to spend hours on this. You are just wanting to create a little bit of surface texture to help the primer and paint adhere better to the surface. In an hour or so you should be able to cover the whole surface area. Don’t waste time going over parts you have already done and don’t spent too much time on one single spot as this will make the final result less even.
Use Denatured AlcoholThis One Is By Far The Best! You can get it on Amazon HereThe final part of the process is to take an old rag and wipe now the whole exterior with denatured alcohol. Denatured alcohol is makes a better job of getting rid any grease still left behind. So always choose denatured alcohol over standard alcohol if possible for this kind of job.
Use Painter's TapeFinally cover any parts that need to be protected from the paint with painter’s tape. The windows and windshield are the obvious places. But don’t forget door knobs and any other small details. This will save you from having to paint round them which can be pretty time consuming.
You Are Now Ready To Paint Your RV!
What you will need
- Latex based primer-or similar
- Fiberglass paint
- A paintbrush or a paint gun
Before you start you need to know how you are going to tackle the actual paint job. Some people prefer to do it by hand. The advantage is that you only need to buy some brushes. Also if you are not confident in using a paint gun it might seem like the simpler option. The disadvantage of hand painting is that it is slower and a lot harder to get a smooth uniform finish. Also you will most likely need to climb on the roof to paint it which can be a bit tricky.
The other option is to use a paint gun. This will allow you to work a lot faster and, assuming you can handle the gun okay, get a nice even and more professional looking finish. If you haven’t used a paint gun before just take a bit of time to experiment and get familiar with it before applying any paint to your vehicle. You can either buy or hire a paint gun depending on what will be most cost effective for you in the long run.
Before you return a hired paint gun, don’t forget to wipe it down with some acetone to get rid of any leaked paint
- Starting at the front, apply the primer using your chosen method. You are aiming to cover the whole exterior with a smooth even layer of the product. Give it a few hours to dry – or however long the manufacturer recommends. Always read the manufacturer’s instructions before you start.
- Next apply your paint proceeding just as you did for the primer. To keep everything going smoothly, use a long fluid motion. This is the best way to avoid drips. Drips can be more of a problem with a paint gun so paint gun try to keep it all as smooth as possible.
- Once again, let the surface paint dry. It will take longer than with the primer. You may have to wait 24 hours and sometimes longer. As always, refer to your manufacturer’s instructions before you start so that you know what to expect. Once the paint is completely dry you can decide if you are happy with the result. If not and you feel that another coat is required simply repeat step 2 above.
