> I have both a TIP 99 pressure blaster and a cabinet using the kit from
TIP as well as a small cabinet from Harbor Freight for soft media and
delicate parts. The pressure blaster needs to be refilled every 15-20
minutes. This gets real old quick! I had planned to modify my cabinet to use
the pressure blaster in the cabinet. But after refilling the pressure
blaster so frequently, I finally ordered the siphon pick up tube. Atleast
now I have the satisfaction of being able to blast continously with out
interuption.

except for heavy rust which takes a little longer. For paint removal alittle
stripper and scraping prior to blasting speeds things up.
> I am weekend car nut/restorer and have little time for my hobby. So If I
were set on a pressure blaster I would get the largest capacity one can
afford. Also keep in mind that a pressure blaster needs to be use out doors.
It makes a real mess! You will have blast media everywere! Much of it will
be lost so you will need to have a good supply of media if you are doing a
large project. For safety you will need head gear and eye shield which needs
to be frequently replacement due to the fact that it also gets etched.
Gauntlet gloves are required for your hands and a heavy clothing to protect
your skin. Needless to say that all this gear is guite warm and you will
soon brake a sweat which of course will fog up your vision! Last and most
important you will need a respirator! The fine dust is harmfull to your
lungs and health! I have considered a fresh air system , but have stopped
here, resorting to use the much more practical Blasting Cabinet. Had I
known, I would not have bought the pressure blaster and protective gear.
Instead I could have spent the same money and had a larger Blast cabinet.
