Front LED Strip Sticky to Touch

On the front of my 2019 Flagstaff 26RBWS is a shallow v shaped LED strip to provide light at the hitch. Last fall I noticed it was sticky to touch. I believe the LED strip was protected by a clear vinyl cover that was not UV stabilized. Anyone else have this problem and what did you do about it? I have tried various means to clean it but it remains sticky and gets dirty on the road.

I've noticed the same on various brands of LED strips. My problem is the black plastic bezel ring around my TT's AM/FM/CD/DVD is the same way.

I don't have your model but I believe you are in the right ballpark.

While mine isn't sticky to the touch, it has gotten very yellowed and hence, not nearly as bright as it was when it was clear.

I have also noticed the same condition you describe when visiting other units on dealer lots. Sometimes on not very old units!

Many plastics do get sticky when they get old. Certain chemicals migrate towards the surface after a while. Try some WD-40 on a rag in a small area to see if it removes it.

The bezel on your head unit should be acrylic. If you look closely at where the bezel meets the wood of the cabinet you can locate a small notch. Tape the blade of a small screw driver and GENTLY pry the bezel off. Now you can clean it. The bezel hides the four screws that hold the head unit in place.

I tried several different liquids including WD40, GooGone and some other chemicals collected over several decades as a plastics engineer.

My current try is sealing it with a clear acrylic spray on top coat. This seems to be working and I will continue re spraying on a 48 hour interval to build up a protective layer. So far the stickiness is contained. Only time will tell.

Our unit is only three years old and I noticed this last year.

That was going to be my next suggestion. Iíve had to micro-mesh, then clear coat plastics in the past.

I have a 2019 Flagstaff 29KSWS that has the same issue. Please advise if you find a solution.

"Certain chemicals" are the plasticizer. Concurrent with its migration is an increase in brittleness of the product. This what was behind the huge scandal and lawsuits with "PB" plumbing. The tubing was fine, but the elbows and tees got so brittle after several years that they would spontaneously fracture in the walls--usually at the inside corners where the stress concentrates.

So far so good. I have masked off the front of the trailer to protect from over spray and am coating the LED with a clear coat. I am using Rust Oleum Clear. I have applied two coats with a minimum of 24 hours between. I will continue until I use up this can of paint. No longer sticky to the touch just question as to how long it will last.
