Evo-Stik is the adhesive used by the majority of repairers and manufacturers in the UK. Only use that for key corks and tenon corks as it's flexible and is applied very thinly.

B&H used it on everything - nearly all B&H clarinets and oboes I worked on with their original pads had them glued in with Evo-Stik, even on 1010 clarinets with Gordon Beeson pads, so they couldn't be adjusted if they weren't seating.

For pads (skin, leather and cork), use shellac as that will set hard and offer excellent support, yet adjustments can be made by melting it again should you need to. It can be dissolved in alcohol (meths or isopropyl) as well as acetone, but don't use acetone on plastic bodied instruments as it can melt them.

Use meths or isopropyl to degrease any areas where adhesive is to be applied to ensure it will bond, that's after removing all traces of the old adhesive. For keywork, you can use acetone to remove Evo-Stik from them if there are stubborn spots - you can apply a drop or two of acetone to old key corks or felts to let it soak into them and that will make them easier to remove.

Contact adhesives like Evo-Stik and similar work best where both surfaces are close fitting - the best kind of tenon slots are completely smooth and flat as that will have maximum contact with the tenon corks as opposed to grooved tenon slots where the tenon cork will only make contact with the peaks (even though the adhesive has coated everything). If you have grooved tenon slots, then you can either machine them flat or fill them in with filler (superglue and wood dust) and then machine them flat to provide maximum surface area and maximum contact with the underside of the strip of cork.
