RV Exterior Painting

Yes but no writeup. It is the same as painting a car. Just prep the surface, mask, and spray a good quality automotive enamel.

If there is bare aluminum exposed you will need to prep it with an aluminum cleaner/etching solution such as Alumiprep and then coat with an aluminum specific primer or the paint will not adhere very well. After the primer you can use body filler to level out the surface and then seal, prime and paint as with any other vehicle.

I needed to paint the fender skirts for my trailer as they had faded. A quart of good quality automotive paint and the necessary reducer, hardener, clear coat etc. Added up to about $150.00..Decided to just replace them with new from the factory. I would hate to buy enough paint to do a whole trailer. $$$

B.O.

Yup, here's my process: Clean with Jasco Prepaint conditioner (TSP substitute), fill any holes or other, sand, rinse. Scuff with 3M pads, rinse. Prime with DTM primer, caulk seams, prime back over caulk. Paint with a good quality acrylic latex paint. Paint accent colors. I have an airless sprayer and masking equipment.

I've actually seen good results using Sherwin Williams A100 and a roller. Not car show quality, but....
Prep is key.

Yup, the prep makes the job. With old paint surfaces, removing the oxidation makes for a much better bond. Scuffing and using a cleaning chemical like TSP takes care of that.
