G'day,
Been reluctant to ask this for a while now but i've had no luck finding what i needed. Perhaps it's easier for me to ask specific questions.
What i want to know is what sort of prep should i undertake and what paint is needed when restoring metal parts such as foot pedals, shifters, seat frames etc. These are your average bits and pieces that over the years have lost their finish. My old method would have been to give a light rub back and spray with fiddly bits enamel but this has proved to be a bad idea with regards to longevity. Everything eventually flakes and scratches and i want something that is a bit more hard wearing, with a nice smooth finish.
So, what type of paint should i use? Is enamel ok? Do i need to use a primer at all? How do i go about sanding in between coats?
Cheers guys appreciate the information!

Fiddly bits is pretty shit, some of the better pressure packs like White Knight and Wattle etc are a lot better wearing.
That said, i like to use engine enamel for pretty well everything, its really tough for a pressure pack product.
REst of your prep sounds good, sand, clean, spray. Depending on the product primers are either needed or not, for your regular pressure packs then you will need them, for something like engine enamel it should be fine to go strait on.
Cheers.

I would use POR15 or KBS top coat for the above parts. I particularly like the POR15 chassis black finish which is a semi gloss. The paint is hard wearing.

All very valuable information and i like the engine enamel idea. So priming depends on the actual paint product? I didnt know that... Should i be fine wet sanding in between coats?
I might think about POR15, i have a similar product from the states but im not sure how it would look painted on?

Most enamels go happily over a nice clean metal surface.
Some are just garbage, and compared to proper coatings there all garbage, just depends on how carried away you wish to get.
For parts like you suggested any of the above options will be fine.
Wet sanding between coats would be ok if you leave it to cure properly, thats getting very keen though lol.

Yeah not too interested in it being perfect, just wanted a sort of smooth finish but having thought about it i think thats more about sanding the intial surface rather than in between each coat.

what i might do is give everything a coat of stripper and get it all back to bare metal. i'm presuming engine enamel will not need a primer for bare metal?

Shouldnt do mate, i never bother.
A lot of those pressure pack primers do more harm than good.

Not needed but a squirt of 1k etch primer helps adhesion.

Powdercoating in a non UV non wear situation can be fine, but i personally generally dislike it, and honestly would prefer engine enamel over bare steel.
