Re: Scratch x
I would only use scratch X in specfic areas, have to say its hard work by hand ! if your impression is like giving it a polish/wax ? then some hours later and knackered arms you will relise its not ! its very hard work using scracth X and should only be used in the area its needed.
(Megs Scratch X have a video on youtube showing you how to use it )
This of course depends on the depth of the scratchs you have if there still above the paint then it will be possible to get them out, if there to the undercoat then it would need pro painting.
The best way of dealing with them if there light is to machine polish them using machine cutting pastes etc.. that would match the paint and thickness of the paint , so as not to damage the top coat.
if you use the coloured t-cut type products there just a type of filler polish and will only last a matter of days rather then months, so good for masking a car for sale but not as your daily driver as all that effort results in very poor durability.
a lot of the detail sites recommend only using a sealant as your LSP (last stage product) and not a wax as this can mask silver and not let the max shine through, i have seen amazing results from claying, then using a good paint cleaner like Carlack 68 nano, then a good glaze , followed by two coats of a sealant , lots of people swear by Jetseal 109 on silver ! once this has all been done it will last for months ! and water will just sheet off each and every time you wash the car, do the wheels with the same products and the wheels will come up great ! and stay that way or at least washing them will be childs play with no heavy rubbing to remove brake dust etc.. !
loads of people will recommend different products but the cleanyourcar site that has already been suggusted is brill and has a forum where i have posted the Alfa results , in the past Freelander , my Jag , and my R1 , and i tend to go with product reviews rather than marketing hype !
what i have found to my cost is ! if you skip a stage or product the results will not be the same and they all say that the paint prep is the key to using sealant and wax without the clay and paint cleaner your products will not bond as well meaning it will not last.
