R&G Fender Extender

[ThunderGuts]

So decided to fit a fender extender; got the R&G one and looking at the install, it uses a thin strip of adhesive tape and four little plastic pop rivets. I get the impression from the instructions the adhesive tape is only a temporary element while fitting the rivets and it's the latter that actually give the strength, but they look a bit puny? Is this adequate, or have others come up with other ways to secure theirs?

Cheers

Replace with small bolt and nut (flanged, or nut and washer depending what works etc) if problems occur.

Never had one flap about (not R&G, but in general) on the bikes I've had with them installed.

Cheers all. I have some small stainless dome-head allen bolts which could prove to be an inconspicuous solution. Glad I'm not the only one who thinks 3 or 4 little plastic pop-rivets seems insufficient given not just the force of the air, but going through puddles and all that water pounding against it.

Brings back memories, mostly used Pyramid fender extenders, removed that spongy sticky sided stuff and drilled 4 small holes through all for the self tapping screws provided.
Then drilled slightly larger holes in the fender/mudguard only so that the self tapping screws bite the extender fender with a thin layer of sealant inbetween.
Finish off with touch up nail varnish on the screw heads the same colour as the fender/mudguard.
Nuts & bolts is a no no on concaved surfaces.
