Hi Guys,

I'm restoring a Victa Mulch or Catch, and I had a couple of questions on painting.

I stripped the axel's and treated minor rust.
I sprayed one coat of Dulux Metalshield etch primer.
I sprayed two coats of Dulux Metal Shield Epoxy Enamel.

I found that it didn't really harden to the level that I was expecting. I left it for over three months, but it didn't make a difference.

I sanded it back to remove the shine, and this time tried White Knight rust guard. I warmed up the parts and paint prior to painting and sprayed three coats three days apart on approx 22deg days in the sun.

It has been over a month, the finish seems better than the Dulux, but still not what I would consider hard. I can mark it with my finger nail.

Am I expecting too much from off the shelf spray paints? White Knight is not cheap.
Could the Dulux primer be causing issues?
Can you recommend any other brands? I don't have a compressor or spray gun, so it'll have to be rattle can.

How hard is the finish on the White Knight hammertone paint?

I've already put a lot of time and money into painting the axel's, I just want to make sure it is going to last and not get damaged easily.

Your help and advice is appreciated.
