A Frame for Cleaning J-Rail Trim

J-rail, also known as rain rail, is the aluminum trim that follows the basic shape of your trailer. Once you've removed it for a painting/resealing project, you'll probably need to clean it of old silicone, butyl tape, paint, moss buildup, and so forth.

Trouble is, it's easily bent while you're doing all this to it. Then it's difficult to get a good seal behind the segment that's tweaked.

To prevent this, and for ease of handling and storage, you can screw the trim onto a wood frame made of three pieces of lumber. Half a dozen screws are enough to hold the trim down firmly enough for cleaning and polishing.
