Bonding agent/adhesive

[Der_Techniker]

Looking at fitting a fibreglass replica RS4 bumper. whats the best route forward to adhere the bumper to the steel bar as per this photo? any good bonding agents or glues?

Bitumen or that stuff they use to bond the windscreens in.

I would fibreglass it on if I were you.
then you can reinforce areas as well

Why not get a Rieger or something like this First Ever RSR A4/S4 B5 Front Bumper Sale :: LLTek Motorsports

Had the offer of an rs4 fibreglass replica for cheap. But think he's sold it now so this may be a dead end. To be honest. I wanted an s4 bumper ideally, to fit a FMIC yet stay subtle, but they seem to be rare as rocking horse poo to come up for sale or rediculously expensive... £300+ 2nd hand!!!!

Sikaflex AT Connect is ridiculously strong not really for cars though. I heard tigerseal is good quite a few people on here have used it to stick on spoilers

tigerseal is very sticky and strong but it is not what I would call an adhesive, it is more a sealant compound.
its very thick and dense and unless very warm is difficult to get into a thin layer.

Tiger Seal is good stuff, seals aswell as sticks!!!

Depends on the bumper also, the Dietrich one i had already had 2 mounts fitted to mount the Audi bar onto.

Sikaflex 252. This is what held my rear bumper Votex attachment on and my sideskirts for about, ohhhhhhh, oh dunno 2 years? Bloody excellent stuff. It was also used to pack out my rear diff mount and gearbox mounts for an extra rigid ride. Cant reccomend highly enough, but does take a while to set.

I believe Grizz will have an S4 bumper shortly that has been modded for FMIC
