[sdiy] Panel Finish

[Tony Rolando]

I was spraying Al diy panels w/ Poly, but I switched to lacquer because 
the poly started to yellow after about 1 yr. I have not noticed the 
lacquer yellowing yet. been over 3 yrs.

That looked great until a few years later when the paper started absorbing moisture and expanding/wrinkling!  So far this toner transfer is working well)  Unfortunately I like black graphics on the bare metal.  I've found several people have posted great explanations for their methods of making professional looking black panels w/ white text, but not black text on silver.  The toner transfer does look good, but I have concerns about the longevity.
