Hi
I am painting some steel rim wheel as a decoration for my home.
I first used a Vaper knotted wire cup brushe to remove the old paint, rust and all the stuff. I really did the work with the brush.
After that I used a spray can of Rust-oleum painter's touch 2 in 1 (black) to coat the whole wheel.
The paint came out great, even on everything, good finish and all that. But as I work to put more color on the rim, I notice that the black paint can be scratched really easily even after 3 weeks of curing.
There is no flake coming off, but if i rub my hand on the rim a lot, I can see black pigment on it. I can use my nails to draw lines on the rim.
When trying to remove a spot where I used a primer with red acrylic paint, I was able to use a wooden clothespin to grind to the bare metal.
I tried another type of paint: Armor Coat Rust paint (alkyd).
Unfortunately, it is only slightly more sturdy after a full day of curing. I can scratch it , with some more effort, with my nails. The pigments seem to be holding more to the metal, but with some intense rubbing, I still get some pigment on my hand.
1) Do I really need to use paint specifically made for rim wheels, or is pretty much any metal paint scratchable?
1.5) Is the fact that my paint can be scratched a proof that it isn't bonded well?
2) Would applying a clear coat hold/protect my work enough?
2.5) If I use a clear coat, I need one that work with both alkyd and acrylic paint, any suggestion?
Do you have tips, company, products that you would recommend to work with metal.
I am gonna do a sword next.
