Title: water scale marks on black car
Post by: javalin on 05 July 2010, 10:40
Hiya

Everytime I wash the g/f's car it ends up with what looks like lime-scale is left on it.  Its been clay'd, polished and waxed earlier in the year so the surface is nice.  I use a wash mit and the TBM.  I use a micro-fiber chammis to dry it after.

Also - its seems to get a light haze on the bodywork very easily - its not clean black not a high-gloss black look.  Is this possibly where I haven't got the wax/polish off enough - maybe it dried in the sun a bit?

What am I doing wrong?  Is it as simple as needing drying towels?

Cheers,

James

i think some pics of the offending haze would be good

have you thought of just running around the car with some QD and a microfibre after you wash it?

have you been washing the car when its been in direct sunlight and on a very hot day?

This can be down to the rinse water drying to quickly, however you made find giving it a good wax afterwards gets rid of the water marks, or like Guy mentioned use a quick detailer and microfibre

yeah its really bad if you let it dry when hot.  Consequence of having a black car in the summer I guess.

The last time (photo'd) I was washing it at 6am (don't ask) and car was cold.  It was fine till I sprayed water over the windscreen to test some glass sealant, then look what happened!  Car was actually cold at the time.

Any ideas?  Have we just got scaley water?

can see the water marks... can't see the paint  :laugh:

here is my suggestions if you can't get yourself an in-line water filter to combat hard water

1. make sure you use a clean wash mitt with the 2 bucket method
2. try washing a panel at a time working from the roof down, dry the panel just after you wash it.. it IS possible to wash panels without getting other panels wet
3. use a drying towel followed up with a microfibre
4. clay, polish and then a few coats of wax will get rid of the marks and lessen the amount of water that sits on the paintwork and increase run off

vinegar sometimes helps. try a 50 50 mix.

Try sheeting the water off when you rinse with an open hose rather than spraying it. With a well waxed car, this will almost self dry it. Then dry the rest with a mf cloth using a QD spray or AG Aqua Wax as an aid.

Thanks Dubber,

I think I'll use some of the megs no80 (or is it 82..?) 3/10 cut polish and then, jetseal and put a few coats of wax on it.  Hopefully that will clear the dullness (oxidation?) of the paint too!  :smiley:

Jeez detailing is crazy there are so many options and ways to egt a pukka finish. This jetseal gets a regular mention though so may need to invest in some of that :)
Where is a cheapest for that stuff?

If you've got a black car then I heard that Poorboys black hole is supposed to be really good and hides loads of marks.
