Either 11FC construction adhesive sealant, or 221 High Strength Automotive Adhesive Sealant. the 221 is dearer, but probably better.

I used Sika-221 to stick my panel brackets on and they're stuck like "the proverbial to a blanket"

What I want to is 2 times 25 cm angle line on both sides on the top of the canopy

because my fibreglass roof has a slight bend in it

and under the fibreglass ribs put a piece of flat Strip with under neat with a fair bit of Sikaflex and

bolted strait true

Hope this is the right way

Cheers John

Well you need a sealant not an adhesive then John. Let the mastic do the sealing and the screws/bolts hold it in place.

Hi Barry

I'am afraid that the Sikaflex is maybe not anough ???
the panel is an 200 watt one so a fair bit of weight in it
and the Fiberglass on the ute is 6 years old ( and a bit chalky )

One of my mate's lost 2 panels while driving that's why I am a bit worried

Thanks John

What ever Sikaflex you use follow the cleaning/preparation instruction to the letter or better. Some need special sikaflex cleaner but other don't.

Go online as they have good info pages

It will not let go if done properly.

Now I'm really confused - the photo shows 2 brackets riveted on (am I correct) and you are now referring to a solar panel sealant (for water protection????) OR an adhesive (to GLUE 2 things together????).

I would never use an adhesive only especially if the fibreglass is aged or flexing - through bolt as you indicated previously.

IF this is the case then you need a sealant and not an adhesive.

I hope this is correct interpretation John.

Why not sand where it's cracked .. Drill a few holes including at the end of cracks and cover with new resin and cloth .. On the both sides so the holds bond it good ..
