Paint stripping off the old paint and found this.
The top layer of paint was easy to get off.
The second and third layer, not so, but there is all this black stuff on the paint under the top layer.
Thinking about it I do have a theory as to what's going on.
People have said to me when visiting as to why I don't just sand it smooth and paint over the top.
Well this is exactly the reason.
I think when the bus was last painted it wasn't prepared properly and this is mould.
Mould has to be killed off properly before painting over the top of.
The saving grace here is that oil based paint has the ability to block anything from underneath for a time but not forever.
This is hard to ignore but if you just painted over the top of this it would no doubt bleed through.

As usual Norman Julian, your attention to detail and not accepting a second best result will show in the final product!

Neil Rickson thanks Neil.

Those who say just sand it back have never prepped the 3 acres of a 1976 F100 bonnet and it shows.. 😉
That said next time someone suggest sanding it back give them some 600 wet n dry and a bucket of water and point them towards some body acreage to be prepped.
As for the mould, it is the bugbear of greentarded waterbased paint & primer.
Once the mold takes hold you have to strip it right back, had it happen on a Volvo that I had and it kept bleeding through.

Pablo E. Laredo I have bought water based stain sealer.
I painted it over the top of acrylic paint that had suffered years of people smoking.
2 days after I put it on yellow stains came through the paint.
Never again would I ever use anything water based to do such an important job.
Needless to say I bought the same brand of paint in oil based and it did the trick.
What most people don't understand with "mould" is stuff like bleech cleans the area where mould spawns but it doesn't actually kill it.
Mould lives and needs to be killed.

Anyone have any ideas on what sort of thermal insulation that can be used between the outside and inside skins of the roof.
Now for me is a good time to do it. It will make for a better and cooler ride.
Pablo E. Laredo
The issue with fibreglass is that it retains the moisture against the panel.
I'd look at closed cell foam(so it doesn't retain moisture).
There is a sisalation that has a bubble wrap thats sandwiched between 2 sheets of silvered mylar that may be an option.
Norman Julian
Pablo E. Laredo yeah in my climate which is cold we can have lots of frosts during winter.
What happens with roofs with no insulation is water runs down under the roof when the temperature rises.
I often wonder if you stuff insulation between two skins, where does the water go. Does it get soaked up by the insulation.
That's why I would really like to get the right insulation.
David Wilson
Atlanteans had fibre batts in plastic bags between the roof and upper deck interior lining.
About 4 cm thick

There is a spray insulation that I saw being used in Canada on the ceiling of a 20 foot container.
