Yes Bob, at least this newbie is learning and enjoying what you share. I
have learned so much from the collective knowledge here, on the Classic GMC
FB page, and the Vintage GMC FB page, that I am feeling more and more
comfortable with the whole rv thing, and in particular, our Glenbrook.
Because you all share, we will have a safer and more fun experience than if
we were in this alone.... Thanks to one and all! Nancy

Subject: [GMCnet] Restoration. Replacing your ceiling panels.

This info is old hat for some. But new owners might find it informative. I
think from what I have found over the years. And this 78 GMC Royale is no
exception. That there has been water infiltration at some point. And this
seems to be the major problem of mold, and odor. What can make the
replacement of these panels a much simpler project. Is to remove the old
ones carefully. As they make great templates to trace out the cut lines on
the replacement panels. I used some 1/4 inch Luan plywood for the ceiling
panels. Need 5 sheets at $14.98 each at Menards. Simple to cut. And bends
well to conform to the curves of the roof. There's a plastic cardboard
that you can get from sign companies that also could be used. It makes more
dead air space for added R value. I did all this work at the start of
dismantling in late Nov. A Little over 3 months ago. In this way I could
discard the old ones right away. I traced, and cut the panels. Then put
an exterior paint on the back sides to keep moisture expansion down. And
reduce the chance of odors from being absorbed, or developing. Then put a
coat of exterior urethane on the front side. Same reasons as the back.
But it would help the contact adhesive bone to the wood. When I install
my headliner later. The ceiling panels must be cut to 73 and an 1/8
inches. This will force the panel to conform to the roof structure shape.
And force them to fit properly into the support slots on each side. To get
the panels to engage the slots. You have to bend the panel like a wave.
Then use a 1 inch long, large headed, self drill/tap philips screws to
attach to the roof structure. Lowe's has them in boxes of 50. $4.98 each.
You'll need two boxes. I did install an R-4 radiant bubble wrap insulation.
Using a special aluminum tape. I took the approach that creating more dead
air bearers had to help. I didn't want to disturb the foam insulation
that's already there. As that original foam helps the rigidity of the
structure, and reduce vibration transfer. Any questions. Feel free to call
anytime. Cell 319-521-4891Bob Dunahugh78 GMC RoyaleMember GMCMI
