Hi Monkeyhanger, The GTD looks stunning and the impact of the G-techniq C2V3 very impressive. As I have tended to use conventional polishes I'd appreciate some advice on the use of the G-techniq C2V3 .On a new car is it necessary to clay it first, followed by the application of , for example, Bilt Hamber polish and finish with G-techniq C2V3. I also understand from what I have read that the g -techniq can be used on windscreens etc and wonder if you have experience of this. Thanks
We didn't clay the car, but we did use the G-techniq G-wash to clean it again thoroughly then dry it. The C2V3 got liberally sprayed on (a little too liberal for my liking!) and then rubbed into the the bodywork and all over all the plastic and rubber surfaces (it protects those too without giving residues). We then rubbed the excess off with fresh microfibre cloths, The stuff spreads really far, possibly as a result of using too much and left quite a tough residue to rub off (we did the whole car rather than putting on a few panels at a time and rubbing off - which we should have done). I decided to rinse the residue off with water (which got rid of most of the excess residue leaving the rest to buff off (when dry). The C2V3 bonds firmly to the bodywork apparently, so no danger of washing off the actual functional coat.
So we did a lot wrong (please benefit from my learning curve, well my dads told him we were spraying too much) in adding too much and letting it dry too long (do 2 or 3 panels and rub it off - then you can probably rub your product saturated microfibre cloth all over the last few pabels without adding more product and minimising waste). You may need a lot of microfibre towels when taking the excess off to a glossy shine - the stuff seems to spread a lot. Treated all the windows that aren't swept by a wiper (I think a treated windscreen would be more bother than it is worth).
There are some perfectionists that would have added a few inbetween steps or insisted on the clay bar first. I'd consider washing the car with ironX first if you're getting a white one, lots of embedded trace iron in the paint on the white Sciroccos (maybe on the others, but remains unseen).
The car feels like it is made of teflon when finished. I do wonder whether to dampen a microfibre towel with the stuff and rub it on. It was quite windy and it looked like maybe 25% of what was sprayed was being carried away in the wind instead of getting on the car, and I probably wrang about 100ml excess from the "wipe on" microfibre cloth.
Beading was excellent once finished and my dad says although it was raining all the way down to southampton today. The car was a breeze to clean (following a 350 mile trip!) with a quick hozing down and a light wipe with a microfibre cloth.
I get my microfibre cloths from Costco - about a tenner for 36!
