paint removal?

[motomagII]

i got pair tracer 3 piece crank arms and want to get rid of the colour on them and polish them alloy is it paint stripper or caustic time anyone know before i try and make a mess/paint or anodidsing please .thanks

[stidds]

If they are painted then use nitromors, if they are anodised then use caustic soda.

If you are not sure which then put on a dab of nitromors and if nothing happens (ie the paint does not blister) then they are anodised.

[daz bmx it!]

As stidds says,but watch the C/soda as if you leave it to long it'll eat the cranks!

Less than a minute dave watch like a hawk i just did £50 worth of odeysey calipers and they turned out ggggggggrreeaaaaaaattttttttttttttttttttt

[dordymush]

does it bubble or anything tom to let you know when there getting to it.also how did you polish them up. oli the orb said to use wire wool.

[The-flying-banana]

Ok dave use a litre of cold water to a tea spoon of caustic attach part to a zip tie or summit so you can bring it out without burning your hand.

Drop it in then you will see it start to bubble "the water" and the water will change colour usually the colour your taking off leave it for around 45sec and pull it out.

If there still anodizing on it dont worry as it will come right off as soon as you touch it with wire wool then you will need brasso waddind also known as duraglit and polish away till your hearts contenet

They say alloy is better than chrome as there's no limit to it shine but it does take a bid of elbow grease

[dordymush]

cheers are tom.i'll try it tomorrow  .

Ps dave once you pull part out rinse well with clear water to get caustic off or it just keeps going 

its like the terminator dave it will not STOP

Hi 

You need to be careful of the fumes with caustic, plus your skin, plus your items.

If you have a painted item, Paramose is great stuff - http://www.paramose.com/ and has different products for different uses.

I've not used this but it's meant to be good - http://www.ecosolutions.co.uk/Home-BaseB.htm

get some goggles if you are nitromorsing. or a full face visor thing.

i stripped the paint off my faze 7 frame yesterday, and little speck jumped up and hit me about 1cm below my eye.
it started to burn straight away. i was lucky, that time!

oh and get plenty rubber gloves. the mors munches them and melts them to your skin!!!

still, life without pain has no meaning, i guess!!

[motomagII]

right got the caustic as its anodising .next q is does it damage the plastic ends etc .?ie do i have to strip the pedals first .if so details or hints on how to do this please thansks

[Rombloke]

[daffyduck]

before polishing you have to buff with (grade 000) wire wool extra fine gear plus watch yer cloths with nitromoss as eats them too
