Nicely done, I sold on it.
I do add the rubber paddles and keep them just off the surface of the tunnel.
I like your thinking. Have done this as well with just flapper disks down to bare metal and then using rustoleum 2X paint and primer . only been doing this for 5-6 years and have not seen any reoccurance of rust. however my time test is really not definitive.I am looking for everyone's input. I have used an angle grinder with a flapper wheel and wire wheel before. I had learned the hard way to definitely wear a good respirator and eye protection. I'm a young (born in 1965) lazy guy just trying to find an easier way to cut through the rust with the least mess possible. I'm not looking to do a full restoration, just want it to through the snow a little better without plugging up. I do add the rubber paddles and keep them just off the surface of the tunnel. I am going to try a couple more applications and see how much cleaner I can get it before trying to smooth the surface better before painting.
That stuff looks just like Evapo-rust. Good stuff.P'Blaster makes a product called Metal Rescue, that appears to make efficient work on removing rust. Check out this video:
I was planning on using either the bath product (shown in the video) and possibly the gel version of the Metal Rescue when I restore my '05 Craftsman.
Chemically eliminating the rust (via liquid or jell product) could reduce risk of either leaving behind rust particles or contaminated metal.I'm not sure why you would use liquids on a bucket when all you need is a flap disk. works in seconds..
What tool are you using to drive the flap sander and grinding wheel?Flap sander and a wire wheel will give you a smooth finish down to bare metal, ... then primer and paint ... real easy and quick ...... my preferred method for all my restores and refurbs.
