Leggz and I lined the inside of the roof frame with Blueskin to keep the painted surface from moisture exposure.
This stuff is used to make wall and roof penetrations water tight. It is ridiculously sticky and a pain to apply in long runs or in our case, into the inside corner of a 3 inch steel angle.
We eventually decided to install it 9 inches at a time rather than in long runs. We could work separately and 9 inch pieces were much more manageable.
My Mom had suggested I use "that big yellow thing" to hoist the frame up to the van's roof. I told her my engine hoist it wouldn't go high enough for the job. A little noodling on her idea lead to the next photo. One end of the frame can clear the van roof using the hoist. Time will tell if I can use it to raise the other end too.
The van wouldn't start to move it in for an attempt. The see through fuel filters appear to be falling apart internally and clogging the gas flow.
Tomorrow is another day. Thankfully.
