I know the easiest is to give the frame to the powder coater and to have him deal with it.
But lets say I want to save some money and and DIY it. What is the cheapest/easiest way to remove it?
And no using sand paper is not an option 😉
just a shot in the dark, but how about paint stripper? 😉
Del will they work for powder coat as it's a PU based paint or are you talking about a heat gun?
nitromoors or something - can but try. it is just paint after all. powder coating is just a method of application.
Nitromors and a wire brush. Watch out though, it's evil stuff.
Ok thanks everyone I'll dig into it 😀
If my old Orange 5 was anything to go by, never again am I gonna tackle a powdercoated frame with Nitromoors - reckon It took near 7 hours in total to get it back to bare metal 😥
7 hours.......... Crap
oxy-acetylene gas-axe?
Yep, attacked it in four sittings...after about an hour and a half each time I got bored!
dip and strip or blast. Stripper may work depending on the powder, but it will be hard work.

Not really, its a different chemistry to most wet paint.
A school of piranha can strip a frame to the bare [s]bone[/s] metal inside ten seconds.
Beats scraping away at it for seven hours, fo shizzle.
To be fair I am wondering about the "new" colour. Part of me is wondering if I should not have it bare with just a PU varnish on it. Other option could be hi viz commencal orange, or a green (probably a hi viz commencal green). I could go back to red indeed.
I have googled for RAL charts, but I can't find anything decent.
OK I am going to make it a new thread 😉
anyway, if you are getting it powdercoated, the painstripping/shotblast is included in the price.
Scraping away at nitromorsed frame means you are truly hardcore. Did my pedals once, quite satisfying in a strange, harmful, toxic chemical way.

Don't think it is. At least not in a paint shop (like motorcycling paint shop). I'll try and dig about who does industrial powder coating.
A mate of mine is a sprayer, sometimes he gets pc'd parts to paint, I could be wrong but I think he uses a lye bath to shift it. Nitromors does work but not very well.

2nd that. I spent a very unhappy approx 10 hrs on a frame many moons ago. Wire brush and niromors + eyes is a bit of a gamble too! A blow torch and wire brush is safer, but always wear goggles. I'd take it to a powder coaters and ask what they use, i'll bet there's an easy option.
"I could be wrong but I think he uses a lye bath to shift it"
lye or caustic soda would be ok on steel, but does eat into aluminium though 😯 (just ask Malcom when he cleaned Ogri's bike with it)
Ah, maybe that's only for steel parts then. I'll see if I can find out what he uses for aluminium. Something horrible and toxic probably 
sorry - thought you were just clearing the paint from your crack. more industrialised methods probably nore appropriate. i also would have thought any powdercoater would blast it for you before spraying?
