Re: preparation of styrene kits for painting

SUVCWORR@... #61581 Larry, I have no doubt what you are saying is correct. The EPA would prohibit the use of Aluminium oxide for an outdoor cleaning where the object and the surface beneath the object are not enclosed by scaffolding covered with an impervious material. The grit being collected and recycled without any offsite migration of the grit or the paint. It was impractical to enclose the Statute of Liberty or a concrete walkway, thus the use of Aluminum Oxide would be prohibited. Your error is in taking this very well defined restriction and extrapolating it to all uses of aluminum oxide. It just isn't so. Using AO in a booth or other enclosure is not restricted in any manner and with proper preparation, it can be used outdoors. Just need to meet all the regulations and jump through all the hoops. Standing in your garage blasting rust off an old lawn mower blade is acceptable as long as the doors and windows are closed. The garage is containment and the only person you are potentially harming is yourself. Just make sure you claen up all the grit. Preferably with a vacuum. While I do not work for the EPA, the government agency for which I do work is responsible for enforcing the Air Quality regulations locally.

Of course you can buy Aluminum Oxide because it is used for things other than blasting but they do not come into your home and stop you from hurting yourself. I talk to the company that did our condo ( because I am a director on the board) It can not be used by them. The directives are out there from the EPA.

The Statue of Liberty was done with Baking soda. The work done on our walks in our condo assoc. was also done with baking soda. Thank you Larry Jackman Boca Raton FL ljack70117@...

I routinely grit blast my resin models, wash them and let them air dry before spraying a grey primer on them. For plastic kits, if I've made a lot of modifications (i.e. filled holes, added rivets, removed rivets, repair surface defects, etc.) I still usually give these cars a light grit blasting; if it is a car that really didn't require those types of modifications, I have been wiping them down with a cotton ball soaked in isopropyl alcohol; I then let the car air dry, and apply a grey paint to them. I think the grey paint will give your finish coat a better "color." Regardless, I always grit blast the plastic trucks; you can mask off the holes for the axles, or otherwise plug them to prevent the grit from getting in there; I usually just blast the truck, as is, then put them in a jar of water with a drop of detergent and stick that in my ultrasonic cleaner. This usually gets all the grit out of those tiny areas and recesses on the trucks; I then use the tool sold by ReBoxx to ream out the axle bearing holes. I think grit blasting the plastic trucks gives a great weathered look for our steam era freight cars. YMMV Jim Brewer Glenwood MD ----- Original Message ----- From: radius158 To: STMFC@...
