One rudder, one elevator, one horiz. stabilizer, two outboard spars, one central spar, two fuel

tanks, I-don't-know-how-many-ribs done and you say the green stuff iznogood?!

Why?

One whole airplane, plus a 2nd right wing, and I'm kinda wonderin' myself. Suppose it might be ok

since I covered it all with green paint?

N701TD should be back in the air in the next couple of weeks. Hum? maybe the green stuff was the

real reason for the axle failure. And speaking about getting in the air. Another 701, built by

Clyde Engert of Towanda, Kansas made it's initial excursions into the wild blue today. I don't

believe he is on the list, but I thought it was another noteworthy accomplishment. Aircraft

performed great and Clyde is now a much happier camper.

Not to take sides on the Scotch Brite thing, but from the archives:

This is right from the Zodiac XL Photo Assembly guides:

Metal preparation for before priming

Gently scuff up the surface with a Scotch-bright general purpose hand pad 3M product P/N 7447+ (plastic pad similar to pad on back side of some sponges found around the kitchen!) do not use steel wool. De-grease the surface with a solvent on a clean rag, such as lacquer thinner. Apply the primer on bother matting surface, let dry, then cleco the parts together for riveting. Only apply the primer on the inside surfaces only, the primer may not be compatible with the top coat or paint!

	




Maybe the green stuff was $$$ as in not enough.

The 3M MSDS sheet for product P/N 7447+ shows that it uses an aluminum oxide

abrasive so it should be correct for use on aluminum. I guess you can't tell

what abrasive is used in the product by its color.

Just please, please don't ever get it near aluminum engine parts. Don't

3M publishes several application documents specifically for use in aircraft.  I have attached them to this message in the BBS forum.  Those of you who get the email distribution will have to go there to get them.



Hope this helps.

Bryan,



So are you saying that the "green stuff" is OK?  I purchased the green

stuff, but could not find a part number on the product, so I don't know if I

got part 7447+ or not.  Since I haven't started building yet, I guess I'd

like to know for sure if it is OK to use.  I haven't seen any red stuff -

wouldn't even know where to get that.



Thanks,

Dave

Guess that since you kinda got this started, can you tell us where you got your

reference as to the suitability of red vs. green? I have enjoyed the discussion and

it is quite a bit late for me since I have mine already painted. I did use a

solvent product called Final Kleen and a tack rag over all surfaces after using the

green Scotch Brite, and I do believe I eliminated all the "green dust" before

primer coats. Seems that there are a couple of opinions as to red or green, but so

far nothing that really backs up one or the other. As I understand so far, green

should clean the surface by scuffing, and red is more of an abrasive. For myself I

think I would use the red only when dealing with a surface that has been previously

painted and you are in the process of prepping it for new paint. And also if

dealing with an aircraft that has a thicker skin than the typical Zenith aircraft

(due to the abrasive nature of the red). But since I've been wrong at least once

before (hate to admit that though, and ain't gonna say when), am open to any

suggestions that will help our sport be safer. And did I say I've enjoyed this

topic? Subjects like this keep the list interesting.

If you are talking about the green scrubbing pads from the grocery store, I

haven't found any good information about that. Someone mentioned part number

7447. I found some information at the 3M website about that. I don't know if

they are the same product. The 3M website has a link to search for MSDS

sheets by UPC code, you might try that if you still have any of the

packaging from the product you bought.

Steve,



I have stripped and repainted 4 aircraft and numerous cars and boats. I have

used the "green scotch pads" with no problems what so ever. I have also, on

occasion, used marine Zink chromate when the aviation specific Zink was not

readily available. I also am using green scotch pads to scuff the surfaces

on my 701.

Just my 2 cents.

My Ace Hardware has all the colors. Just different coarseness. The gray is

fine and the red and green more coarse. I forget witch one is most coarse. I

have also seen some really coarse stuff used for scrubbing floors. It may

not be true to the color scheme.

It looks like the green pads are for scouring.  Here is a link to 3m's site:

Could we please put this OWT to rest. Here is the MSDS on scothbrite 96 (the green ones), in spanish, but thats all I could find.



SCOTCH-BRITE(TM) FIBRA ESPONJA 96, MEXICO

ISSUED: January 28, 2000

SUPERSEDES: INITIAL ISSUE

DOCUMENT: 09-5039-4

-----------------------------------------------------------------------------

1. INGREDIENT C.A.S. NO. PERCENT

-----------------------------------------------------------------------------

PHENOLIC RESIN.......................... 9003-35-4    30-60%

ALUMINUM OXIDE.......................... 1344-28-1   20-50%

NYLON FIBER............................. Unknown         15-40%



I looked through all the msds's for scotch-brite and couldn't find any of the pads that had anything other than aluminum oxide, silicon carbide,  talc, or polyester as an abrasive. The "aircraft cleaning pads" have talc and polyester. The various scotch-brite wheels, grinders etc may be different, I didn't look at them. Select them based upon how abrasive you want them to be, or price, or color if you just like the way marron or grey look in your hand, but none of the pads commonly available contain iron. All of us who picked up our green pads from walmart, home depot, or under the kitchen sink can finally sleep without worrying. Now as far as priming the interior surfaces.........
