I asked the following question related to the Blazer canopy and sealing it to reduce water ingress.
“They all leaked from the factory”
The words of my very good friend Dennis in St Louis who used to work for GM in the 70’s and early 80’
My 79 Blazer certainly leaks as much as anything that may leak.
Of course we are in the UK
Which means GM and the other American aftermarket suppliers are not just up the road.
My question is this.......
What is the consensus on what foam seal to fit between the fiberglass cap/canopy and the body?
Some original GM part or use an alternative type of high density type foam to seal it from leaking ??
Even double glazing seals to be considered
Thank you.
My response from a friend in the USA below.
Thank you Ray
I will investigate various options. Possibly over the weekend.
Dennis used to build these for GM.
His advice.
I don't think you will find a aftermarket seal that will work.Even the factory ones fit like curse word. Once you take the roof off you will see why it's so hard to get them to stop leaking. The main problem is getting the seal to stay in place while you get roof back on.
You will need a couple of buddies to help you. It has to go down and forward at the same time while someone is inside lining the bolt holes up making sure that the gasket don't fall out
I was thinking of making some kind of cross shaped carrier to then lift it all hydraulically on my own.
REMEMBER THIS THING ?
Will see how it all unfolds.

Rian, I had a Dodge Ramcharger in the 70's they were the Dodge answer to the Blazer. It leaked so I bought some roll of rubber gasket material. I tried the foam but it collected water and then it seeped moisture in. If you can't find it you might take a Bicycle Tire Tube and put it between the top and body.
