I just pulled my 26 year old Toro 521 out of my garage corner that has be sitting for the last 8 years not running. I bought a brand new aftermarket carburetor, new fuel line, cleaned out the gas tank, new spark plug, lubed up the transmission, and checked the belts. I pulled the rope 4 times and it fired right up I warmed up the engine and adjusted the new carburetor. I changed the oil and it is ready to go. My question is .........I have a product called Fluid Film in an aerosol can. It is a Rust & Corrosion Preventive. It is used to prevent grass from sticking to lawnmowers, and snow from sticking to snow removal equipment among about a 1,000 more other uses. I was thinking of spraying my entire augur, bucket, and snow shoot to prevent rust as well as preventing the snow from sticking. My Toro has very little rust and I would like the machine to last another 26 years if possible. Does anyone here spray anything similar on their snow blowers here?
