Waxing edges and threads, glue smell

Hello,

Three questions from me: 1. When heating a waxed edge I use quite short time under heat so that the edge colour stays very light brown (Fits well with natural-coloured goods). The wax does melt and the edge does get stiffer and stronger, but I suspect the wax penetration is not that deep. Do you think it's okay for the edge durability or should I try to get really hot with the wax to make it penetrate?

2. After I've done the stitching with a waxed thread I run over it with a light flame, just to melt the wax and get a better shine to the thread. Do you use such technique? Or maybe you handle the leftover surface wax differently?

3. My rubber glue which is based on neoprene gives off some really toxic and intense fumes. Is it the common problem with rubber-like cements/glues or am I that unlucky? :D Do you use some gas masks when working with really smelly stuff?

:)

Cheers,

Radosław
