    I know many of you remove your tops during the summer, but I don't. And with mine being painted black in Texas and too tall to fit in any garage, it gets extremely hot inside. Is there any nice looking way to possibly insulate the inside of the shell?

    I think if you insulate it, it will still get as hot, but it'll be harder to cool off. Dark tinted windows would be the only thing I could think of. The dash puts out a lot of heat. I've found that just putting in one of those sun blocker things in the windsheild has made a big difference in how hot it gets in there. Black in Texas sucks in the summer. [​IMG]


    I've got a mind like a . . . a . . . what's that thing called?

    I was thinking of putting some sort of open/close vent on the back of the rook similar to the kind found in RVs with a small fan on it to help evacuate the hot air while the a/c is running. What do you think of that?

    Ya! Or even just the vents without the fan so the hotter air can escape throught the top so it will circulate some. I'll bet that'll help alot! You could just crack your windows and open the vents. If you need to, later you could add the fan. That'd be cool!

    Why don't you put some insulation on top (like dynamat or something similar) and then make a headliner for it to cover the insulation? I think you can use some trim parts off a suburban's interior to help with the headliner installation. That way you have a headliner in the Blazer top. Just a thought.

    i have an inlaw with an 86 and when he bought his the previous owner had a real headliner installed in the fiberglass top, i think whoever did it used a sheet of builders styrofoam insulation you get from lowes etc.. for about 7$ and used head liner fabric to cover it, and his truck is not nearly as hot as mine, and i am considering painting the roof of my truck white or some of this new heat reflection silver, just on the roof so you would not be able to see it from the ground


    It needs a bigger motor.
    what's in it now?
    doen't matter it NEEDS A BIGGER MOTOR

    I'm gonna get the inside of my top rhino-lined for both the looks, and the insulation factor. I'll let ya know how it turns out.

    I have thought about it for sound reasons. The top reflects a lot of sound around in the 79. The 75 is horrible with no carpet and that top. sounds like a steel drum. Stereo sounds better with the roof off than it does on.
    There are ribs in the top that as long as they don't have a peice of steel in them have enough depth to put some short screws in. I was going to get a sheet of 1/4 inch plywood and cover it with some headliner material. They have screw hiding snaps at most trim shops that you can cover with the same fabric as the head liner fo a finished look. No reason why you couldn't throw some insulation up there in the process.

    It's not my damn planet monkey boy!

    I insulated the inside of my shell. I started out using the insulation with the reflective side. I cut and glued the reflective side to the three areas of the shell, between the ribs. I then used 1/4 inch mfd board cut to the same size as the inside ridge to the shell(about 4' by 4'6" I think I can't remember). I rounded the edges to fit. I then covered it with grey tweed.

    (Now this is the most important part) Have a friend help hold the new headliner up while you drill a small pilot hole. then install screw. If you don't drill a pilot hole and use just the self tapping srew, it will pull out, especially on the old blazer tops.

    I've seen some guys that have rolled white "Kool Koat" mobile home roofing on their tops, and it actually didn't look too bad.
