Did you glue the panels directly to the cieling?
Suspended cielings usually have metal divider I assume they make them in plastic.
I've got a couple of spots that might be a little tricky where they ends of the cabinets stick out a little bit and have rounded ends. I'll figure out a way to do it.
I'm redoing a Winebag Elantra. They have a product called ClearGlass 2 that i literallyjust like liquide clear coat. They have a neat little aplicators. The sponge for around pipes with a slice to put your fingers in and then it's wrapped in a (don't know if spell check will get this one) shamy.
They even have DIY labels for the outside of vehicles "called waterslide". If you use the right program you can make really big emblems to but on the RV.
I'm going to run it by my accountant, but I bet I can take a Home Office Deduction even though this one still runs. It has to so I can dump the sewage.
Love this site
