Powdercoat vs. Paint

[nuggethead]

Hi again Ozzers,

After fuel tank leak on my bike (620 ie 2003) and living by the sea i have some corrosion/oxidising issues with my rear set (no not my ass). This has led to the powdercoat lifting and flaking off on both rear sets. I want to have the rearsets sand blasted and refinished and am thinking simple re-powdercoating or applying a paint finish. Thinking of a chrome finish if paint finish.

Wondering if anybody has experienced this before and/or considered  the options detailed above. Some advice on the pluses/minuses of either would be great.

I am also concerned at the ease of which some of the nuts/bolts and various other small bits on the bike easily rust/oxidise. The bike is always garaged. I believe there is no other option than to head to the local stainless shop and attempt to match up n purchse new bits. Is there a trick to stopping corrosion like this?

for the bolts you could buy the stainless steel bolt upgrade kit from monsterparts.com

then...this is from my bicycling fountain of knowledge...you could buy clear nail polish at a chemist for a couple of bucks and coat the heads.

this all comes with a big MAYBE as I'm a newb

If the rearsets are alloy, both podwer coating and paint are only a temporary cover at best. 

Best for alloy is anodising! 

Many colours are available and they can be done to varying grades of hardness also.

As for bolys, just take them all down to your local bolt shop and they'lle able to supply anything and everything you want a lot cheaper than buying the bolt kits. 

And if you want to really get carried away, go to a good tool place and get some stainless polish and a polishing mop, and mount the mop in a drill and you can polish the stainless up like chrome that will never tarnish or flake. 


Otherwise I personally would go paint over powdercoat. Powdercoat tends to be brittle and chips a lot easier than paint.

+ 1 on the anodizing. Powdercoat is a pregnant dog once it chips and the salt air gets underneath.
With the bolts, specify 316 Stainless (marine grade) 304 is ok but will still lose its polish in the sea air.
Make sure you use anti seize ( except where the manual specifies loctite of course) as you tend to get more binding with the stainless bolts.

+1 on the antisneeze, very important unless you are very good at getting out busted bolts. (Read "pain in the arse)

what process do wheels undergo?

painting or powdercoating? then people polish them of course....what is available there?

thanks in advance and for not calling my advice stoopid!

Are you asking this in case you get a bike with white wheels? (you racist)

Yeah, go to the local bolt shop, make sure you have a few bolts with you 'cos they will charge you $1 whether you buy 1 or 10, it's like a gold coin donation.

even though various places will happily sell stainless bolt "kits" be very careful what application you use them for, stainless has nowhere near the tensile strength as a regular steel bolt and may shear in a high load application, there's a link which shows bolt shear strength of stainless and high tensile of different grades. to limit corrosion if i lived by the sea i would apply CRC after washing it but keep it well away from the brakes for obvious reasons!

Usually powdercoating on wheels, not much chance of "Flex cracking" but chipping is easy!
