which fibreglass adhesive?

[OlberJ]

Need to bond some fibreglass body work to a steel frame. What's the best adhesive to use?

Any recommended brands?

Usually you use more fibreglass matting and resin

Epoxy, it will stick to polyester and steel. Polyester resin does not adhere (very well) to polyester once it has cured, it delaminates easily. Be sure to rough up the area to be bonded and make sure it is clean, ie no oil/grease etc etc. You can thicken the epoxy with "flock" which makes it thicker and also adds strength. It is commonly used when bonding frames etc in on gliders etc.

this - there's a variety of fillers available for epoxies for different purposes.

Indeed, t`is true but for structural bonding I`d be inclined to use "flock", cheap to buy, simple to use and readily available
