I recently got my first project saw  ( SEZ) in pretty good shape but someone has been fixing scratches and worn paint with a spray can  The carb cover has been painted red  among other places on the saw. Has anyone come up with a quicker method to remove old paint other than the good old fashioned way with elbow grease and sandpaper  I would think the chemical strippers would etch the aluminum. |

I've used chemical strippers on the magnesium parts with no problems. Never noticed any reaction to the metal.

Here's my suggestion ;D
Take the clutch cover and strip the inside using a paint stripper that is "water cleanup" and see what happens. The underside of the air box cover would also be a good place to test. Wash the part using blue Dawn dish washing soap and water first because Dawn is a good degreaser.

On my project Skil, I stripped the aluminum cylinder of paint, and the zinc alloy carb body of paint. Both times the stripper did not harm the metal in anyway.
The Zipstrip type strippers are solvent based, so I don't see any problem with any metal.
Any stripping method that uses an alkaline or acid to etch metal clean would be a different story (easy off oven cleaner, muriatic acid) These products would likely harm metal. DO NOT USE!

I have been using a chemical stripper that is sold at the auto parts house for aircraft. They use aluminum and magnesium extensively on aicraft, and I have never had any adverse affects from it other than is is hard on skin. Always wear eye protection and protective gear.
