Dig out ALL sealant you can get to on roof. down over the front and back.
Small tip hole on nozzle.
reseal with "Sikaflex PRO.

then get a "heat reflective" paint kit.2 cans .
Coupla coats No 1. Coupla coats No 2.

first one thick and flexy, forms a good seal\bond, over everything.
Top coat a white Reflective Plastic coating.(They do colour to suit.)

My last van is 8 yrs still going well. This van Last yr.

Then panels over that keeps you nice and cool inside.

Dat paint does tree t'ings. Seals. Reflects, and cools.

Macka, can we have a specific brand name of the "Heat reflective" paint please?

Something I can do a Google search on. Googling Heat Reflective paint brings up too many choices.

Cheers
Jim

 I wish you wouldn't put up links like that..... I just spent over an hour looking at the various products on offer biggrinbiggrinbiggrin

The 3M Extreme Sealing Tape 4412 might be a better option as it's 2mm thick as opposed to the 4411 tape at 1mm thick. I looked at the product brochures and the 4412 tape looks like its better for sealing over ridges/unever surfaces.

Jim.
Cans long gone.
From "Aussie Paints" from memory?
Was around $210 (then) for a 2 pack 4 + 2 ltr can kit.

Did fully My 6.5mtr Roadtar and this 535 Coromal full height , both

I had 5 panels on roof over coating. rollout door side. another roll out in sail track other side of van.
NEVER put van in shade.
Like Darwin for 3 months or more. Annually.
Qhite comfy temp wise. Inside.

Friend who built a fairly large live in shed up here put me onto this one. Several of them had used differing makes over the yrs.
His is\was at Balgal Beach. I sorta think he has a house there now?
Lovely and cool inside. Surpringly so.
as is my van\s.

Jim, as you found there are many sorts of heat reflective paint
We had our house roof sprayed with a Dulux product (cool roof) which gave excellent results (again it wasn't cheap). Refer www.roofguardroofpainting.com.au/
I recall seeing adverts in caravan magazines for the paint that macka mentioned.

I don't know that it reflects the heat but trials I did with Telstra several years ago proved that regardless of colour, the internal temperatures of roadside cabinets reduced by seven degrees - enough to reduce the failure rate of key circuit boards. We had three identical cabinets - one was normal "gum leaf green", one was painted "white" & the third was "mint ice-cream green" - they brought the wrong tint (but it won't work, said the supplier as it's not white) but both painted cabinets gave the same results.
I found that on a normal day eg 30 degrees, I could not touch the ordinary cabinet for a more than 20 seconds but the others, there was no limit!

As said.

It DOES work.
Trick is no matter how many bottom coats.
2 of the thickest top coats you can apply.
is better that 5 thinner.
The pigments\Ally strips in it do the trick.
Thin layers. less pigmentation.
Another trick.
Foam roller. and only go ONE way. it's thicker again then.
Just back\forth over seams.

Have fun. It IS worth the money for both reasons.
w\proofing and insulation.

Jim, I just saw this in a post about Member's rigs.
Thermoshield was used - see thermoshield.com.au/ - as you said there were a number of products available.
