I've used Purl Wax for years (using different Purl waxes for different conditions). Purl wax is supposedly among the safest "organic" ski waxes, where "safest" connotes no PFC emissions during application, and thus no PFCs entering the lungs. I've applied Purl inside the house without concern for extra ventilation or the use of a respirator.
I'm considering switching to Swix CH4 for improved performance. No doubt many of you are familiar with this product (a hydrocarbon wax) and its virtues (often as a base layer covered over by a top layer specifically for racing).
Ignoring issues of base preparation, iron temperature and so on, I have three specific questions concerning CH4.
1. Is a hydrocarbon wax safer than a fluorocarbon wax re. PFC emissions. I've read what I can find in this forum, and the consensus seems to be that the "wise man" uses a respirator while applying fluorocarbon waxes. Online sources that discuss the issue, such as http://www.skiwax.ca/tp/waxroom1.php and http://www.environmentalhealthnews.org/ehs/news/ski-wax-chemicals, have caught my..."attention." But hydrocarbon wax may be a different case.
2. Can CH4/hydrocarbon wax be safely applied inside the house without additional ventilation?
3. Can CH4/hydrocarbon wax be safely applied without use of a respirator?
Additional information: My interest in Swix CH4 is not as a base layer, but in its durability for recreational purposes (i.e., less frequent waxing).
