Bonnets - stone chip removal procedure

I was offered an Amethyst (same colour as my car) bonnet for my SAAB 9000. As those who know him will testify, for the previous owner keeping cars clean and shiney is not particualrly high on his list of priorities - it had never been cleaned let alone polished in his two year ownership, so it would be interesting to see how well the bonnet came up with a bit of detailing

As you can see from the test section it did come up rather well.



So well in fact it showed up the multitude of stone chips.



So I thought I would explain how I plan on making these less noticeable. I am sure it is not the way the professional would approach it but I have used this technique before with some success.

Items required: A can or two of lighter fuel, small tub of matching or similar colour paint (Humbrol enamel paints are ideal - I used black), polishing pad (ideally lint free), protective gloves.

1. Wipe surface over with a cleaner - I use lighter fuel.
2. Squirt lighter fuel on to pad and add some paint.
3. Apply paint on to surface ensuring it is well rubbed in to the chips.
4. Leave for half an hour and repeat the procedure at least three times till the chips appear 'full'.
5. For large stone chips get a toothpick and dip in the paint and apply to hole.
6. Leave for a few days for the paint to dry.
6. Using 3000 grit wet and dry rub over the entire surface, taking particualr care with the larger toothpick filled stone chips.
7. Machine polish and finish with a wax.

This will get rid of 80-90 percent of pinholes.

UPDATE: I have given the bonnet a couple of coats.



Original photo for comparison



I know it may look a bit frightening but a steady nerve and taking time will reap rewards. As explained it will reduce thee appearance of chips rather than remove them completely. Anyway another coat or two and then I will leave it for a while for the paint to harden.

Here is the bonnet after a test section using Farcela Scratch paste on a rotary. You may find there are a few pin holes that may have been missed, so use a toothpick and paint to fill them.



It will then have some Menzerna Final Finish - test section shown here:



....and will be followed with a a cleaner and wax.



Almost complete.



Bonnet has not been waxed at this stage. 8-)

Wow!! I was going to post something up about how to remove these, the front end of my car is really let down by the flurry of little white specks! I'd be terrified to do this to my car, but looks like it works well!

May just have to attempt this one day!

When you sa "and add some paint" how much? A dab onto the pad? Diluted by the lighter fluid?

Good work... I've got some Audi paint ready to do my front bumper, though I'll probably use a fine tipped art brush or graphics pen nib and work over them one at a time due to the shape of the bumper...

BenB - I would say about a 10p piece is enough. The Humbrol paint pot gives a good size amount when you put the pad over it and tip it over and yes give a good squirt of lighter fluid on the pad first. After about four applcations you will find the pinholes/sky at night effect will have disappeared. Repeat the proces until you are happy.

A tip: To keep the pad moist between applications grab it in the gloved hand and take off the glove still holding the pad. The pad will then be inside the glove staying soft ready for the next coat.

Felondnb: I did my front skirt about three years ago (this is next on the list to do again) using this method and again it does work well as you can rub/fill in those areas you cannot get at with a brush or pen. Try a test area and I think you may well be pleased with the results.

Detail: Re: Invisible Man - or to be more exact self timered shot was used to stop camera shake as I could not use a flash.

Very good improvement indeed. I'll be bookmarking this thread for future use when our Passat receives some much needed 'bonnet attention' after some 60K of motorway miles. Just haven't plucked up the courage just yet

Do you hold the 3000grit by hand or use a block/pad behind it?

BenB - I use an old cork block - don't try it without some sort of block, ideally something not too hard such as rubber. Use plenty of soapy water as a lubricant and do a small area at a time, keeping the strokes in the same directions. As I don't have a paint depth meter I made sure I didn't take too much off - a way to check is when you have finshed, wipe the panel and leave to dry. The entire panel should have a flat dull finish.

Here is a shot showing the dull flat sanding finish along with a section showing a first pass with Farcela.



Hope this helps
