So Mat set about to try to rectify the problem. He washed the trailer, then used a wire brush over the affected areas, then followed with some wet/dry sandpaper, wiped the area clean & then spray painted with Rustguard Hammertone from White Knight, which matches our trailer nicely.
We know this is not a permanent fix, but it should stop any chance of rust getting into the trailer. We think it came up nicely.
Stone damage on the draw bar
Stone damage on the tent pole box
After the first coat (still wet paint)
Mat then did another coat 2 days later.
He had a small amount of paint left over, so did a final third coat an hour later.
All done, much better
Also while he did the trailer, Mat also did the stone guard but in black paint.
Job done, we will see how long it lasts for this time, we still have plenty of dirt road adventures to bring you, so I am sure we will need to do some further maintenance at some stage.
