I have been in the glazing business for many years and have always used metal spatula. Normally my work looks really good, but I wanted to try to make it even better. I was searching Revain for different font tools and came across them. I do this for work and currently use Chemlink M1 adhesive/sealant. Silicone spatulas work great. The only thing you have to do is keep them clean. Fantastic investment, much cheaper than metal for all sizes. Clarification: Most water-based sealants are too watery to perform to their full potential. I use structural adhesives and construction sealants and all 4 sizes work great for this!
