Hi all
Ive raised this before but, still having problems with a Kashi restro. Previously it was suggested that I try different dye (Dylon) which I have now just finished BUT it still looks like it has powder on it. Its been sanded down to 1200 grade and its smoother than a baby's butt.. With the smallest amount of water, it looks perfect. Indeed, the second pic below (bottom of the pic) shows a finger print mark and even that amount of grease gets rid of the whiteness..

Any thoughts? I was about to wipe it with a TINY amount of WD40 but open to better suggestions??
PS: the expert bloke on BurnerWorld said he will not touch blue Kashi's as they never turn out right. So perhaps the above results are just epidemic of all blue Kashi's??

i had a nos blue one that kept going like a powder on the surface.
i soaked it in gloss amourall from halfords.
done the trick and when it did start whitening a bit again a quick wipe over and it was sorted again.
worth a try.

If you're desperate you could try painting it. Shat did I just say that!!! :-\
At least it's not a set of Skyways. Plasti Kote Super in a satin finish maybe??

Just an idea :-X

carefully flame polish it with a blow torch, job done shiney shineey

t-cut or glass-cut followed by a polishing mop?

Hey mate - I just tried baby wipes but they did not work. Ill see if I can get hold of some window wipey things like your Amourall..

You serious?? ??? Sounds a bit severe.. Besides, the saddle has a lovely surface; it sanded up lovely.. I just the whitening affect when dry..

Hey mate - really dont fancy painting it. As mentioned, the finish is really lovely and when wet, it looks totally MINT! Its just this darn whitening.. :(
Off to my workshop to try some of my special polish, ai!! :coolsmiley:

I had this problem, I wrapped it in 200g of lean back bacon, left it in the fridge for 48hrs. Try it.

I'll just add it did fook all.

Why not try a bit of back to black spray from halfords or your local garage? It was always good at giving a sheen to black plastic bumpers that had gone white. Just give it a spray and a wipe every so often. :daumenhoch:

you can get that armorall in a matt finish that might look better than shiny
-
Blue Tcut?

Despite several attempts, this did feck all (although my Kashi does now have clamydia)..
I also tried Window Lean (like the Amourall suggestion).
I then tried my polish wheel but instantly stopped as the dark impregnated polish started to show on the seat.
Also tried some "All Metal Shine" and this looked great for 20 mins this has also now started to dry with visible whitening..
Sucks..

As mad as it sounds - the blow torch is probably your best bet. I've seen it done on other blue seats.

Right the trouble here is with the sanding process
the colour was added when the seat was made - when finished, it looks a solid colour and has a polished surface for a shine/solid colour look
if now you take sand paper and rub it over, this will leave small lines - small flakes/scratches will lose the solid colour and turn it a white/clear with each mark
now if you sand the seat with different grades, it will look whitish - this is what you have - now by putting water or grease on it, it will join where the sanded lines/flakes have lifted, making it look solid again
adding heat will join the flakes/lines together and making it look solid - there will be a point where it heats up and becomes smooth, as the heat melts it it will look shinny
dying it with dylon will only coat/cover the out side - if it has small lines/flakes they will not dye so well and will still look whitish
how long did you leave it in for ?
sanding it down to a smooth or very flat finish might look better and dye better, but heat will give it a more solid colour look after it has been sanded like that
you could also try another way after heating up - it will have a smooth look when heated, but you could try rolling a pattern on to it - the original seat has a slight texture to it - rolling some thing like sand paper over it or some thing similar might give it back it's pattern again ?

Cool.. So, I presume the Before/After pics are using the blow torch method?? If so, very impressive results and the before looks exactly like mine..
Regarding a blow torch, I dont own one so could I just carefully use the gas rings on my oven?
"I'll just add it did fook all." - yeah, I laughed at that aswell :)
ta all..

Prob about 3+ hours using boiling water and lots of salt. I dont think the problem/solution is with the dying

Cool idea.. Not sure I will try the pattern effect as sounds tricky but, defo gunna try the heating up (assuming it is okay to use a gas oven ring instead..).
Some great help in this thread - big thanks..

Bendy is right, its the microfine scratches from sanding that make it look powdery. The sanding marks are visible in your pics. I have seen flame polishing done a few times and it does give great results, if you know what you are doing. I would be tempted to get some plastic polish and give it a bloody good go with that first.
-
You can use Autosol on plastic :)
-
trouble with the gas rings is you can't see the change and what is happerning
you could see if a hair dyer will do any thing - a heat gun would work but being carefull at it
polishing will work but you will have to work at it ;)
-

Yeah, I just found this out :) Tried the oven on a very small area and like you say, it went from doing nothing to small bubbles that now need to be re-sanded.. >:(
I'll try a hairdryer next..

what window lean did you use.
the amourall i was talking about is for making your tyres shine etc on ya car.
i've just red about using a heat gun on vw bumpers. puts the color back in them after they have whitened so might be worth a go.
-
I'd try a blow torch personally
OR
contact russj on burnerworld or raleighburner and he might advise you the best way to polish plastic

Did you try Oldschoolace's T-Cut idea? I've used it on black plastic and it worked for me. :daumenhoch:
