Wa dah try D&D epoxy..... better than aquaz...
Wa stick monti kat vertical rock senang sekali. Tak perlu pakai banyak.
First kena uli sampai rata about 5 minutes. Lepas uli, biar dier jadi keras skit for further 5 minutes. Lepas tu pacak lar. Kalau kena air, jadi licin tapi bila kena batu, melekat baik. Tunze kena of dulu la.... atau slow speed. Curing about 24hours.
Harga kat petmart tigabelas bengkak.
