My trailer has Linex applied. It originally had a cheaper product applied by a friend that built my trailer. We had originally talked about having Linex done, but to save some money on the build he attempted the lesser product. However about a month later, several areas began to peal off. They were not large areas, but probably an issue with the prep work although he told me that he followed the instructions. In his defense, the guy is a fabricator, not a painter and I was the one that turned down the Linex to begin with.
Well I tried to patch it, but it looked like crap as it was uneven and the product was a pain to work with (started harding in it's own bottle). I then contacted a local Linex dealer to have the trailer sand blasted ($150) and then they applied their product with their UV protectant. Total for that was about $1,000. However they broke several of the lid's hinges as they let the lid slam back after removing the lid's gas lifts, and then didn't want to take responsibility for it saying it was a unique job! So I had to have new hinges welded on (which burned the surrounding Linex), and then the Linex dealer had to touch up the new hinges (for another $300 total). I should have had the Linex done upfront as my friend would have taken care of it with his own vendor. You get what you pay for!
Anyway, the box inside and out is sprayed. The product is awesome! The trailer will never rust, and mud and grim spray off easily. No kidding... about nothing sticks to it! I actually put a rubber workout mat inside as otherwise stuff just wants to slide around.
What I'd tell you upfront is to have Linex applied and do the entire trailer. Don't go with the cheaper stuff as if the prep work isn't right you'll be dealing with it later. The Linex is much thicker. I towed the trailer off-road around Utah a year ago and no rock chips period. I see some trailers that are painted and I can imagine the owners just have to keep repainting them. Not with Linex...
One thing I'll also say is to make sure that you have everything welded to the trailer that you want, as once the Linex is applied, you can only bolt things to the trailer. I wish I had had a few more attachment points welded to the trailer before the Linex was applied.
This is the cheap product...
This is Linex...
