Given the choice of placing your can of silicone lubricant you use to clean and lubricate the balls and pushrods on your printer next to it, in the same general area as your hairspray, don't.... ever.... do.... that.

I grabbed the silicone instead of my hairspray and started to spray my bed... for a split second, once.... for one part... and have been paying for it ever since.

I've now lost 4 prints due to adhesion issues, which basically never... ever.... happens for me.

The silicone has seemed to sink into my granite bed rather readily, and so my stupid mistake has been very difficult to eradicate.

Bah.

Another round of razor scraping and acetone, and... 

Printing...  again.
