With Info gained here ....

With information I received in this column regarding primers I set about restoring my vintage mountain bike forks ...




This is how the forks looked at the start. id never seen rust like this before. The original finishing process may have involved chrome plating or anodizing. The rust was in horizontal lines across the forks... very strange :?










After lots of graft this is how they are now ...

And here is how i did it...
its all in the prep. Because of the deep pitting caused by the rust i thought the forks may have been beyond salvage. lots of high build primer and lots of sanding was the key to covering the pitting and bringing them back from the dead.
i was going to have the forks satin black but after spraying them satin black i wasnt happy with the finish so lots of flatting back with wet, wet and dry
more coats of satin black... more flatting ...then more flatting ... followed by a few coats of 2k clear coat. this stuff is the dogs .... dont waste your time the stuff from Halfords, HS 496 Auto clear is what you need ...




Etch primer, high build primer , satin black



wet sanding (use washing up liquid in your water to stop paper clogging) reveals deep pitting caused by rust ...



Deox gel (very low odor, doesnt burn your skin, safe to use indoors)



Its a faff to use...but once coated, wrap with cling film to stop the gel from drying out. leave overnight...





Yiles ! are they worth bothering with ?



Panel wipe between every paint stage ...



Etch primer ...



Lots of flatting before High build primer ...







Lots of wet flatting ...



Final coat of high build primer ...



And this is where i would have left it ....



But i wasnt happy with the finish...

So more flatting, couple more coats of satin black then clear coat...











Im quite pleased with the results. Taking my time, Carful preparation and decent product proves you can achieve acceptable results with rattle cans.

you have made a good job but to be honest I think the rust will come back through time. ive never seen marks like that before on anything. interesting.

Yeah took a while but the best thing is unlike working on my car which is my daily driver, so any work done on the car needs to be done on a daily basis ... This was done at my leisure.

Yeah it might do! Still, it was good practice using this combination of product together.
