Spring Update #2

In case anyone was wondering, T1N Sprinter Paint is crap. I knew it wasn’t the best, but my recent experiences outline its poor adhesion. An example is the solar panel brackets on my van. The photo below is an intermediate bracket. These were attached with 3M VHB tape and sealed with clear silicone. In less than 1000 miles the paint to primer bond failed completely.





Here are where the forward brackets attach. These were attached with rigid polyurethane adhesive and #10 sheet metal screws for security. 1 of three had the paint bond fail completely. The others were showing signs off failure. The back brackets were bonded with 3M 5200 (flexible polyurethane adhesive). These brackets are 100% still attached and show no signs of failure. I prepped and painted the area and installed rivnuts. The brackets will be bonded back in with Sikaflex 252. The rivuts are directly over/inside a roof support, so this area is quite sturdy.





Given this evidence I strongly suggest that fasteners be used to attach all critical loads. Adhesives are still a great idea for extra strength, but the stock paint is the weak point.


Here is the Espar external temp sensor. I will be mounting this on the driver’s side wall panel above the bed.



The pull-out pantry shelves are built. Had to cut a piece out to remove a paint can…





All the general lights are installed.





We test fitted Blum soft close overhead cabinet hinges. They are a very high quality product. Not cheap though.







The shelf above the rear doors is also installed. There will probably be a mesh net on hooks securing gear up here.












I have the parts for a water separator and fuel filter setup on order. Given our intended travel destinations (rural areas, Central/South America) I figured it was cheap insurance.  Mounting might be a challenge though.

I have harnesses and light strips made up for the exterior lighting. I will be bonding those this week as well. LIGHT UP THE NIGHT!

  1. I love the saga of the paint can.

    Thanks for all the great information. I'm in the middle of a conversion right now.
