Just wondering if anyone has tinkered with this product yet.

I'm pretty sure it won't work well on the alloy cast boxes many of us use.

I've dabbled in using spray on photo-resist to etch hammond enclosures.  I haven't gotten it working quite right yet, but once I do I think it will be a pretty easy way to get high quality etching.  The only problem is that the resist is some nasty stuff and I have no place to experiment with it in my small apartment.

I got all the needed chemicals from Philmore.  You just spray the resist onto the surface of the box, put your design on a transparency, expose the box to light, develop the resist and dip the box in the etchant.  Unfortunately just thinking about the chemicals is making me queasy.

Here are the results:



As you can see I didn't put the resist on thick enough and got etching where I don't want any.  Once I figure out the ideal way to apply the resist I should get good looking boxes, and the total outlay for materials was only $10 or $15.
