We have been using the other yellow product at the big green box but found that often stock level was inadequate or product was too old/ pass the useby date. We were recommended Adheseal by another tradie and we have never looked back. We have used it for roofing and as a stud adhesive and it performs very well. It performs well under heat and UV. We just now buy it by the box which makes it very convenient and its competitive on the price. It saves us buying one box of sealant and one box of adhesive and then we have throw them out if we have not used them by the useby date. It saves weight in the ute as well which is always a bonus. We have also used their wayer proofing products which are fantasic and well priced.
