感謝！用哪種sealant好呢？

噴的？ https://www.costco.com/flex-seal-clear-spray%2C-2-pack.product.100737729.html

還是傳統caulk？ HD有很多種，比如https://www.homedepot.com/p/Henry-209XR-Extreme-Rubberized-Wet-Patch-Black-Roof-Leak-Repair-Sealant-Caulk-10-1-oz-HE209004/100001308

需要買一大桶嗎？也沒有多貴： https://www.homedepot.com/p/Henry-208R-Rubberized-Wet-Patch-Black-Roof-Leak-Repair-Sealant-0-90-gal-HE208R142/100041225
