Has anyone ever used
naval jelly to remove rust?
I'm pretty pissed right now…I'm using the steel saucer sled & I think I got a bad batch….
With the first two I made a year ago, I ordered from Amazon and they came in their original packaging. I recently picked up four from The Tool Warehouse in NJ, where they had as many as 400 sleds in their warehouse in February. These were handed to me out of the box. No visible damage, but something must have been up with them because all four have been bad news since I started stripping them.
With my first shields, I used Kleen-Strip Aircraft Paint Remover and the paint practically slid right off the sleds. With these four, I couldn't get all of the paint to bubble up, and as a result quite a bit was left on. I was out of the Aircraft, so I then used some of the Citrus Stripper they have at Home Depot. Even that required quite a bit of scrubbing--hours of it, in total, for four sleds.
There was black rust underneath the paint on three of the four sleds! ?!?!? Not only that, but within an hour, all four sleds flash-rusted with giant dark spots, and two of them rusted in the back with hundreds of tiny brown-grey specks.
Conditions were fine---not too humid, in fact it was pretty much the same exact weather as when I stripped my first sleds last spring.
I've tried to sand some of the rust out using the technique I would use anyway to give the spun metal look, and no dice. The only thing I can think of using to salvage these is naval jelly, but I've never used it before. Is there any hope that it can actually get out these black spots & the large flash rust stains?

I am SO peeved right now, especially because one of these was going to be for a friend.
