Seein as you guys were so good on my last question.......

I have a 96 CB750 F2N. Lurvely bike...but the paint has swirls in it.

What is the best way to restore it back to a decent finish (apart from re-spray)? bowdown.gif



Cheers,

The best thing i can think for that would be a fine grade hand glaze, like a polish but not chemical based like t-cut but has a fine cuting quality in, often used in body shops to finalise a paint job. 3m do a nice hand glaze, but for a harder cut you could try Ferecla G3 polishing compound, same sort of thing but more of a paste with more argessive cuting.

But the best man for this is DP, he is the undesputed god of pigmentology bowdown.gif

Ok steve(DP puts GOD head on laughcont.gif )
Swirls? little round milky scratches?
i would try Farecla G6 or G7(most spray shop suppliers will stock a tube of this stuff-they'll try to flog you G3 which is designed for modern 2pack applications)-its more user friendly but good old t cut is as good as any providing you have the patience.

if compound doesnt work you could try wet flatting it VERY CAREFULLY with some handsoap & 1500 grade wet & dry paper.use STRAIGHT LINES not circular motion. then once its got a dull uniform finish ,polish it with cutting compound (G6/7) or t cut.
the only problem with this is if you go at it too hard & break through-its a respray!

the most common prob with older paint is UV rays causing a milky effect, or the laquer breaking down & showing what appear to be tiny scratches.
the above are only stop gaps-once the laquer starts to go its a slippery slope, but if you're patient, you can achieve good results.
if you want a chat then bell me on the mobile no-its on my website.

Oh god of paintwork....

If i use farecla or T-Cut, can this be used in circular motion or does it have to be back/forwards...

Cheers

Back/forwards Steve, will work best by hand
if you have a polishing mop then its gonna be roundy roundy, but for some reason it never shines up that well by hand(going roundy roundy)

One last one then...
My fork lowers are sh** Badly marked. Is there anyway to get them looking good or must i replace them...

Cheers,

Steve

marked as in?
if there alloy then wet & dry 1200/1500 grit will clean them up then polish with solvol, then clear laquer.
if painted then 800 grit will do, then paint-easy innit?

if you get stuck PM me-you get a quicker answer that way.

Forks - If alloy, initially rub down with @800 wet and dry, then a medium polishing mop - from Cetem or similar - attach to cheap high mains speed drill (B&Q do a good one) and add a few drops of T-cut as a cutting compound to polish up and remove the fine scratches the wet and dry left behind. Autosol works fine, but not too good on the mop I find. Just use as a final manual rub.

If painted, I have just done the following on my ZZR. Brief overall rub down with 800 wet and dry to remove pits/stonechips on the front and to get a good key eslewhere. Not too harsh as this will only remove the paint altogether which you will want to keep for actually protecting the forks! As with all things associated with painting, preparation is everything, so take time over this.

Then I applied a can of plastikote metallic black. Old trick I use here is to immerse the can in hot water for about 5 minutes and shake thoroughly - up and down not side to side. The heat from the hot water expands the propellent inside the can, and also thins the paints a little.This means the paint exits that bit thinner with a higher velocity so giving a more even coat and reducing blobs etc. You have to be a bit quicker with your spray hand though. Appply several thin coats, and give it about 5 minutes before applying the next. I got a good hard finish on mine, and I am tempted to leave it as such rather than apply a final lacquer just in case the lacquer reacts with the paint - as has happened with me twice before - A good artist known when to stop.
