Okay, not to pile on the new guy, just to add a little safety note regarding oil filled heaters. I have one and I assume it is similar to the one GG is using (the link didn't direct me to the product, so I gave up, sorry if the proct differs). It has two wattage switches and when you switch them I've noted a spark through the vents in the cover. Thus, I'd never turn it on or off when any fumes were present. Only to preheat a space - spraying later after it was off - or much, much later, ie: no fumes, for drying.
On the safety issue as a whole I think the idea is for folks with experience (I don't have anywhere near what quite a few of you do) to be sure to err on the side of caution when making posts. Don't assume that the whole forum has the body of knowledge to avoid hazards, obvious or subtle. GG, I'm sure you'll contribute to the community here.
