Respraying Rockshox Lowers

Thinking about spraying them white (currently silver). Yes, yes, it's just a vanity project.

Obviously I'll need to remove lowers and ensure no paint on the insides. But, tell me - if I remove the seals from the top - can I re-use them or will I need new? Does it just rely on me being careful and delicate?

Provided your seals are still in good condition then you should be able to carefully lift them out and re-use them. Might be worth ordering a spare set just in case though.

Funny you should post this as my Lyriks are away getting sprayed at the moment, from white to black

I'm a dab hand a spraying things but the forks needed a service anyway, and the guy can get them professionally painted so I thought why not do both together

Here's his FB page if you decide you don't want to do it yourself. He certainly knows his shocks and forks, and prices are much better than TFTuned et al....

What about powder coating? reckon that would be more durable

Powder coating uses heat. You don't want to heat fork lowers.

I'd rather put any cash for new seals/tuning into a new pair of forks sometime in the next year

The Lyriks will last forever if you keep them running nice

Most fork lowers are magnesium? Powdercoaters won't do magnesium (there's a good reason for it, which was explained to me years ago by Andy at Triple S, but I can't for the life of me remember what it is now, lol).

It's not a good idea to heat any lowers unless you intend to replace the bushed afterwards.

You can use a hair dryer to remove bushes, which won't generate enough heat to do any damage

Not a good idea to take out and refit the same bush. They will deform.

Sorry, I meant damage to the lowers

It’s a softer metal, susceptible to heat (becomes brittle) and is combustible. If it does combust then you need a special extinguisher as water and the like will only accelerate it.

I think some powder coaters will still do it mind you, but I think most others will say no.

You'd need much higher temperatures than powdercoat cures at to risk it combusting. It's magnesium alloy, not pure magnesium.

Haha yeah that's a good point... lowers wouldn't melt.

I wonder why some powder coaters don't like mag then? Maybe the oven heat is still enough to make it brittle?

Possibly (and your face wouldn't thank you if your forks snapped, lol). The reason Andy told me definitely made sense, but it was so many years ago I can't remember what he said now, lol. I'll have to ask him again sometime. If he says no that's good enough for me though, and I wouldn't let another coater do my magnesium engine covers after he'd said no (not a load bearing part, but expensive to replace).
