Now that it’s winter you may find that your resists don’t
want to stick onto the glass properly, especially when using cheap
glass. You can eliminate this frustration simply by warming up the
glass. Use a small general fan heater and blow warm air on the glasses
while your setting up the resist. Don’t make them too hot though
as this can have a negative effect on the resist by shocking it and
creating a melt down situation. All you want to do is take the chill
out of the glass (ok Brony).
When applying the resist to the glass there is no need to bash the
living daylights out of the resist with the burnishing tool. A firm
burnish is all that is required and I think that too much burnishing
may wear the resist down in the little spots. (ok Chris).
Do you sometimes have trouble getting the resist to stick down on
a dual curved surface? The short answer is don’t use that type
of glass. But if you have to you might try peeling the cover sheet
off before it is completely on and then just thumb pressing it on
to the glass.
Blasting pressure in your pressure pot should be 20 - 40 psi. If your
confident that you have processed the resist correctly and didn’t
try to re-invent the wheel in the making of the resist, have a go
at the higher end of 20 - 40psi. You’ll get even faster etching
and also considerable depth will be achieved fast. Myself, I like
to use 40 psi.
DOING A RUN
I recommend that you wash out your resists in gang sheet form and
after spraying the gang sheet up you lay it onto out on backing paper
to form a sticker. You can then easily cut up the resist and stack
it, then peel it off and apply it to the glass.(please Brony)
Do not gaff tape the glasses up for protection (are you crazy) - this
will double the time that it takes to do the job. Make up a black
rubber cover mask and use this in the cabinet to protect the exposed
areas of the glass. Please call me and I will explain it to you if
your not sure. Using the rubber mask may appear clumsy at first but
persistence and dilligence will overcome this and it’ll be easy
after a short period of time..
If you’re not getting excellent results fast and consistently
or if you still get blow outs please call me and we’ll set you
straight. There should be no blow outs at all with Rayzists Sr2000
resist.
Looking forward to hearing from you.
