Check with Bugjuice, didnt he do his frame a little while ago? On his older ZXR, not the 636.

I would make sure that it can handle been sandblasted as alot of heat gets generated by this process, soda blasting might be better.

What is the price comparison between sand blasting and soda blasting?

Careful what media they use, talk to them about it, I got my steel frame sand blasted in wgtn at an industrial place & it looked withered afterwards, fortunately the powder filled it in enough. An ally frame would have disappeared I bet.

If they have a brain & have done similar they will advise what (bead, sand etc) to use, if they go “never done one before mate but leave it next to the tractor wheel” then walk away.

Walnut shell blasting is what you want

Why not get the frame paint stripped? Abrasive blasting is good for rust removal but if its only paint your getting rid of try getting it dipped.
It's been a long time since I was involved with powder coating (20 years) but then it wasn't water proof..powder coat bare steel and it rusted. I am sure things have changed since then but we used to have to galzanise steel before powder coating then, it would be worth enquiring first.
I would have picked a high build paint (single or two pot mix) as a more durable frame coating, gives the same thick coating but is weather resistant with better surface gloss and damage resistance. Talk to a car painter?

G'day mate,
Find a place that can blast the frame using an organic material (ground up walnut shells) or plastic (looks like ground up Lego blocks). Sand or glass bead can wreak havoc because of the heat the process generates. When yo do find a suitable place, ask to see some of their work before you hand over your frame. I've seen some horrendous damage done where ferous oxide grit the size of sugar grains were used to paint strip an otherwise serviceable frame. Tread cautiously!

Arkro can also do some great colours including Metallics and Pearlescents. I have one of their colour charts here, they even do the Gold Wheels for the Subaru dealers so alloy is not a problem.

If you want to see the kind of finish they can get, have a look at my bike. I am in Whangaparaoa during the day and Saturday if you want to come out this way.

This is correct when powdercoating steel. It does need to galvanised before powdercoating to prevent rusting below the powdercoat surface causing the powdercoat to bubble and flake off.
