Back when I sent a welcome email to Miss Mustard Seed, a.k.a. Marian Parsons, she offered to send me some of her products to try. How totally awesome of her, right? But I had to admit, I’d pretty much worked with most of them already.
However, I thought I vaguely remembered reading somewhere that her Tough Coat Sealer had been re-formulated to have more of a matte finish since the last time I’d used it. So I asked her to please send me some of that.
So the other day when I was contemplating what product to use to seal the rusty toolbox I brought home from that garage sale I wondered if I could use the Tough Coat Sealer.
The toolbox isn’t terribly bad on the outside, but the inside was quite rusty. It was rather greasy and dirty as well.
So I did a little google research. I googled “using Miss Mustard Seed Tough Coat Sealer to seal rusty metal” and that search took me directly to this post from Miss Mustard herself where she conveniently addresses that question in the comment section. She also mentions the reformulation of the Tough Coat Sealer in the post itself.
So, full steam ahead.
I first scrubbed the toolbox well with Dawn dishwashing soap and one of those 3M Scotch Brite scrubbies. I tend to use dishwashing soap when I’m trying to cut grease. I suppose that TSP substitute would work just as well, if not even better, but I haven’t tried that.
I wasn’t aiming for perfection here, just an easy clean up and coat of sealer that would allow me to store stuff in the toolbox without it getting all gross.
Once the toolbox was dry, I simply brushed on the Tough Coat Sealer. I gave the inside bottom of the toolbox a 2nd coat just to be sure I was taking care of that rust, while every other surface only received one coat. Here’s how the inside looks after …
Much improved, wouldn’t you say?
Although it’s cleaned up and the rust is sealed, I also added a paper liner just to make it a little prettier. I used one of my favorite October Afternoon papers, and just laid it in place with no adhesive. If it gets grungy over time I can easily replace it.
Here is how the toolbox looks on the outside with its coat of Tough Coat Sealer.
I did save the label.
I think I might use the toolbox to store my ribbons.
I don’t really know why I have such a fascination for rusty old toolboxes.
Something about them just appeals to me, especially when they are used for something unexpected, like vintage ribbon.
Looking at the ‘before’ and ‘after’ pics side by side you might be thinking that they don’t look all that different, but that actually was my goal. I wanted to seal the rusty metal so it wouldn’t rub off on things or continue to deteriorate, but I also wanted to retain the rusty aged patina.
The Tough Coat Sealer did that perfectly. It added a tiny amount of shine and it darkened up the color just slightly as well, but for the most part it didn’t change the look by much.
So the next time you need to seal some rusty old metal, consider reaching for the Tough Coat Sealer.
And speaking of Miss Mustard Seed, tomorrow is her workshop with Carver Junk Co. I think they may still have some spaces left and tomorrow is supposed to be cool and stormy, so a perfect day for hanging out indoors and learning about milk paint.
I’ll be there and I’d love to see you there too!
