My teardrop has had a bit of a refurbishment. When I built it, I figured I knew best and painted it with oil-based enamel paint.
As mentioned here on the forum, oil-based paint doesn't flex enough for this application. It cracks. Over time, I started getting checking in the roof plywood. Not too bad - I could just give it a quick sand and reapply more paint. But, I didn't consider this a long-term option.
So I removed most of the exterior hardware such as the racks with the solar panel and awning, the mounting brackets, the vent covers, hatch latches etc, and sanded the whole thing.
Then I applied an acrylic membrane called Liquid Flash. It is water based, microfibre reinforced, UV rated for exterior applications and used for sealing seams in roofs, and sealing timber decks.
It can also be used as an under-tile membrane in bathrooms.
Horrible stuff to apply, recommended final thickness 1.5 mm. Struggled to achieve it. In the end I was rolling it on, which worked but left the surface very rough.
Then it was time for a mostly decorative, but also functional in that it will help with the water exclusion, topcoat. Water based exterior house paint. 15-year guarantee on a house. Should be fine on an always garaged teardrop.
After the first topcoat, I hand sanded the entire surface, which greatly moderated the roughness from the stippled (?) membrane. Then two more coats. The roof is white, as even on a moderate day the orange was measurably hotter than the unpainted surface.
The colour is called Nullarbor Sunset. I've crossed the Nullarbor, and I don't remember the sunsets being so ORANGE!!!, but I like it anyway.
Nearly ready for teh winter camping season.
