Fellow's what is the best way that you have found to remove the blue from O S max L A engines? Thanks
-
I have done several of them. First, I crock pot it in Prestone (aluminum friendly) anti freeze. Then I soak it in straight acetone.
With an acid brush cut down to 3/8" long (the bristles), I brush off as much as I can. I also use a bamboo skewer sharpened on one end and flattened on the other. Make it flat enough to go between the head fins, and sharp enough to go into the small space in "OS" on the head.
Use acetone!
Good luck, Jerry

Have you tried ordinary paint remover or paint stripper? If you have any pieces of a broken blue case, try a propane torck and see how hot you have to get it before the coating blisters. Keep the torch moving when you heat it, and heat it slowly at first to get it near operation temps. I don't like the blue color either (what was OS thinking!!! maybe just a blue head??" but don't know if it's worth the trouble to get it off.

I did a couple with glass bead blast. Leaves a nice satin finish.

I paint all my engines...

Hi Gil, here’s one I did a couple years ago using the orange based eco paint stripper and a toothbrush. It left a nice citrusy scent to the engine and breath. When a club member asked why I would do such a thing I told him “ so the engine might regain some self respect”.

Bill would you post a picture of the product used or give the name of it?

You bet

If'n you don't like "OS Blue", try spraying with some yellow.
Yellow + blue = green
Green is a more pleasing color, anyway.
(might start a trend)

You bet
Thanks!

You guys have got it all wrong...........the best way to "remove the blue" is to VOTE 100% RED on Tuesday, November 06 ! We ain't tak'in no prisoners ! ... y1

Giveaway number one is that it’s not just an O.S.46, it’s an O.S. ”LA” 46.
Giveaway number two is it’s wearing blue fingernail polish...

I am with Floyd. Green is better.

I just crock potted mine. D>K

Allergic to blue Gil? No pun intended.

I use Hoppe's #9 and also their Gun Scrubber spray and an acid brush cut to about 3/8".
works great.

I like it! You could paint it red. Somebody offered powder coated engines 10+ years ago, but I doubt the heat transfer would be as good as the enamel that OS used. I'm not a fan of anodizing for engines, because it tends to fade and any minor scratches look terrible. However, you can buy small powder coat kits from fishing tackle places, like Barlow's.

Lol. Gil's blue LA 46 ain't a pretty blue la 46. Stripping it would be doing it a favor! But they come out very nice looking when stripped

Kal Guard ! is the Yoshimura GS 1000 military spec coating . Heat Dispersant ,
Some micro fibre finish to multiply the surface area .

I do not know which oven grease remover is available in the States, but there are some strong, aggressive brands, containing 10-20% caustic potash (Potassium Hydroxide), surely. It removes anodized surface* of any color. Use rubber gloves and safety glasses!
After using rinse immediately with hot water, maybe with some vinegar.
*it works on Castor oil's residues, too

Might work anyway...the OS LA engines are painted. It would be nice to know what kind of paint, but current info suggests enamel is likely. H^^ Steve

Dave T yes indeed I am VERY allergic to blue.. So be it..

It's an old plastic modeler's trick to use Easy Off Oven cleaner to take paint off of old car bodies and such for repainting. It takes the paint off, and does not harm the plastic. But it says right on the label not to let it come in contact with aluminum. It would really play heck with an engine crank case. This definitely wasn't one of OS's best ideas. If the engines didn't work so well, it would only make them easier to ignore!
