sealant that doesn't stick like S#!t

[Farmer Piles]

Exterior grade window silicone. Cheap and very effective. Seals and holds but doesn't bond like Sikaflex, etc.. Used it to seal around my windscreen very effectively.

Arbomast BR sealant. it's butyl so doesn't set but remains 'sticky'. Can be used above and below waterline.
