Homebrew PCBs

I don't think so, but not sure. Like someone mentioned last week, 
autobody shops have a horrible time dealing with "Fish eyes" in the 
paint.  This is caused by silicone "waxes" people apply to their 
cars to keep them shiny and new looking.  I know that laquer thinner 
doesn't seem to remove it good enough to prevent problems. Don't 
know about acetone though, never seen the body shops use acetone.  
However, I scrubbed the boards good with acetone prior to 
transfering the toner.  

Gosh this is frustrating.  What was working so perfectly now works 
horridly.  I hope to get some time to focus on this and get to the 
bottom of it in the coming weeks.  

Also, for what it is worth, I tried many different ink jet papers 
(glossy stuff), pages from magazines, toner transfer paper, and the 
pulsar transfer paper, and something else of which I can't remember 
now.  All yielded nearly identical problems, in other words, none of 
them performed better than the other - so now I know I don't have to 
buy the expensive papers anymore - just use the glossy papers :-)
