Ok as most of you know I painted my baby a nice Purple, I still have not rubbed it down and cut/polished it as we ave not had great weather.

My question is how and what is best to do this?

I was told by a guy that does bodywork to wet sand with 2000 grit and then buff and polish it up, my only concern it I don't want to wreck my new paint work so not keen on doing it unless someone in the know can reassure me what to do, what to use and how.

Any info would be great :) or if anyone fancies helping I am willing to pay to ave the work done.

I think your best bet would be try find someone nearby that has a paint gauge so you can measure how much laqour is on the car (prob with a new spray paint it should be pretty health) then go from there :)

i'd imagine sanding it down with 2000 shouldn't be a problem :)

First have you got a 8" polisher/multi speed 8" angle grinder that will take a mop?


Yes rub down with 1500-2000 wet/dry an use plenty of water it carries the dust and grit away and prevents any scratching, then polish with a sponge mop using one of the proprietary finishing compounds, at about 2-400RPM, everyone has there favorite but faracla G3 is as good as any, this will give you a nice gloss.

If your not used to using a polisher then have a practice on something first as if you linger on angles or corners you can go through, and you may want to use a slightly less aggressive compound, but it will take longer to get a good finish.

as you did the painting yourself davie how many coats of clear did you put on .using a paint thickness gauge will not tell you what the thickness of the clear is , it gives you an average paint thickness of the all coats that have been applied ie primer , base coat and clear. so for colour sanding and polishing it depends on how much orange peel is in the clear and how long after its been applied. plus remember that if you have any runs sags or inclusions in the base coat they wont come out by rubbing down the clear you will go through it and will have to re clear the panel

The was no runs in the base coat at all the runs which are at bottom or rear bumper are in the clear coat.

The violet colour is mixed in with the clear and that had 3 coats and then I applied a further 3 coats of clear alone over the top.

I could always rub it down and do a few more clear coats but using a better place to spray and my better gun etc...will that help?

I'd take it to a body shop and get it done professionally. I've done a few before and it's far better to let the pros have a go. They have all the gear an it saves you buying the wet'n'dry, block, mop and heads, cutting compound, anti-hologram polish, hand glaze.... By the time you've got all that you may as well have saved yourself the trouble. :)

I like your thinking, I will check out places unless anyone knows a good bodyshop that will do this or detailer in or near Edinburgh, don't mind traveling but now too far.

One thing if you take it to a body shop they will give you no guarantee not to go through any of the clear/tint as they didn't spray it in the first place.

This is very true indeed, I'm not so worried about them going through as there are 6 layers of clear in total 3 with the pearl in and 3 just clear, I can't see then burning through all that to get to the black base coat?

I think I will try a panel myself see how that comes out, I have my big grinder/polished anyway, after I wet sand what's best to cut it with and then polish it with? I have some G3 is that any good?

if your planning rubbing down and re clearing you need to use 600 anything less it will end up peeling off. if your rubbing down to remove orange peel runs start will 800 then 1000 then 1500 then G3 and if your using a grinder type polisher make sure its a variable speed one as you can end up leaving burn marks in the clear at high rpms.

yes davie low speed and a small amount of water and make sure your mop is clear from dirt and old compound as that will make swirls in the clear. just do a small area first to get the hang of it then when your happy with the finish crack one with the rest. its a pitty your so far away as i would have came down to help you out.
