The adhesive sealant attaching the glass of my Electrolux ceramic hob to its metal trim/edging is no longer adhesive/sealant and needs to be replaced (see image).
I don't know what the original sealant is, but it is black and seems less rubbery than silicone: it holds a fingernail impression. Two questions:
Assuming I need something resistant to (moderate) heat, spilled boiling water/hot oil, hob cleaning chemicals, etc. what adhesive/sealants are recommended/appropriate? Note that the adhesive does not (now) need to be especially strong (originally the hob hung from the trim, but it is now supported) and should be replaceable/removable (i.e. no destructive chemical bonding to either the metal or the glass).
Tips or tricks for removing the existing sealant along the other two edges (so that everything can be thoroughly cleaned.
Please note that I am in the UK and would strongly prefer recommendations that can be satisfied from domestic suppliers.
UPDATE 1
Electrolux were contacted and replied that the trim would have been factory fitted and they could only recommend (what I would expect to be an expensive) "repair". A DIY alternative is therefore required.
UPDATE 2
In fairness to Electrolux it should be noted that one can see at the corner metal brackets that would support the hob, if the cut-out were correctly sized. The cut-out was however both too big and uneven and none of the brackets engaged significantly with the worktop, thus leaving the hob to hang.
I would say that the lip of the brackets could perhaps be wider, but had it been well fitted the current problems might not have occurred even with the existing narrow bracket lips.
