I am interested in the pros and cons of aluminum vs fiberglass top for Cobra trailers.

My experience, having owned both, is that the current production glass to Cobra trailers keep the glider cooler and drier than metal top trailers.
Neatly done repairs are much easier in glass. I am experienced in both.
When the finish deteriorates, my opinion is that it is easier to refinish the glass trailer. This involves surface sanding to get a clean, slightly roughened surface, followed by a couple light coats of spray filler to clean up surface defects, orbital sand with 220 grit, and then spray with acrylic urethane.
The metal trailer, if the paint is bad, requires stripping to bare metal, etch, conversion coat, epoxy prime, then paint with AU.
FWIW most of the damage to either is meaningfully reduced by simply getting them out of the weather. This also keeps the glider cooler which slows aging.
In my view the dominant consideration is how well the trailer protects the glider that costs somewhere between 8 and 20 times what the trailer does.

I am 100% with UH on all points. Get a fiberglass top you will not regret.. An auto-body shop can paint a fiberglass trailer top for you for $2k, probably less than the insulation cost for an aluminum top.


The insulation costs about $1,200 at current exchange rates.

Default Cobra trailer aluminum vs fiberglass top

How does one go about having insulation installed inside an aluminum trailer?
Are there specific spray-on materials that are commonly applied that auto repair/painting shops would know how to work with? Are there some specific materials one should avoid? Seems like the material needs to be fairly abrasion resistant. Is the outgassing of some materials potentially damaging to a glider?

All the glued on carpet in my trailer is falling off for the second time and I do not look forward to redoing it all when a spray insulation may do double duty as padding for the glider bits and pieces.
