Chapter4: ...stripping with Paint Stripper
ok, so first of all you splodge it all over the pedals  (mine contained Ester, Methylsilfoxyd, Ketone)


... i did it outside, and put a plastik bag over the trays afterwards and let it soak for about an hour
It then looked like this


for scraping the gunk off i used these

..however the one hour soak wasn't enough!

...so i repeated the procedure and let it soak overnight outside.

Next day, after scraping

....now it dawned on me. The paint stripper clearly had worked better on one pedal than on the other.
My guess was - it was rather chilly outside - after a short while the stripper gets into this gel-like, if not even mucus-like state, and the stripper apllied after it once gets into this condition does not properly apply -- hinting towards the main problem: the chilliness (was around 8°C) is detrimental to the stripping process altogether.

chubby:
Don't know about cold having an effect on the stripper, but I've had pairs of things where ones taken longer than the other to react  :chin:

fischflo:
No - it was the cold; that's why one pedal was ok, while the other one much worse.

So i moved the next stripping session to the shower. ...And let it soak another night.
Left the ventilation on all night






...i'm well pleased. THe finish aint perfect - one mistake was to use a toothbrush. That works fine, but the bristles dissolve after a while and leave a problematic coating :10_2_12:.

Even after one or two more soaking and scraping sessions there are spots with paint. ALSO there are like spotted parts. Weird thing is they seemed to have appeared (every time) right after i wiped off the last bits of the stripper/ dissolvent off. -... i suppose, again guessing, that the remaining particles harden quickly once the dissolving wet coating is gone.  ------> THERE must be a trick to avoid this.

But i'mm well happy anyway with the general appearance of the pedals. So much that i think i will drop the polishing. I heard a dremel is the way to go - i however bought a polishing top for a power drill. I don't care about a few scatches, and i don't want to loose the orangey apearance of the surface the ped still has on many spots.

Phase5: .....polish
..

There you go.  :daumenhoch:
