Help with peeling lacqure

[retromadness123]

Hello guys just needed some help I have some laqure peeling from my bonnet and wanted to know the best way to resolve it, I only work with aerosols due to not having a compressor or paint gun, so what would be the best way to tackle this or is it a full bonnet spray job, all help is greatly appreciated in advance. I'm trying to upload pictures through taptalk but they don't seem to be up loading I will try again in a bit

You can pick the edges of the lacquer off and blow it in but it will o lay last so long. Sanding it will damage the base coat, you’ll get away with solid colour but metallic will not look the same, eventually you will need the bonnet repainted.

Yes, assuming you are on a mobile device, just use the website and click ‘desktop’ at the bottom of any page, then you will get the option to upload the pictures.

From experience - You may has well just bite the bullet and repaint the bonnet - if it's a metallic or pearlescent you are going to struggle with both aerosols & colour match - although it's not impossible but if you have little experience in this type of work you would be far better off placing it in the hands of a professional bodyshop

I had some great success last year on a Merc which had been repainted up one side but the lacquer was peeling in places.
It was a pearl white basecoat.
I picked off the flaking edges, then a very light rub around the edges of the lacquer with some 800 wet and dry to try and feather it as much as I could without touching the basecoat.
A quick wipe with panelwipe then masked off the surrounding area an inch or two where the bare bit was then sprayed it with this..

I left it to dry for a few days, another rub around the edges with wet 800 then t-cut the bejeesus out of it and some polish.
Came out mint, I then traded it in to a dealer the next week and he didn't even see it.

That aerosol lacquer above is fantastic stuff, I've sprayed bike tanks with it and it lays on as good as a gun, I love it.
It is quite expensive though, though for a small area by the time you take into account a compressor running and the thinners and materials used for cleanup there is maybe not much in it.

There's always going to be a texture difference, even if you throw down 38"s thick of clearcoat and polish it back. I did two areas of my car with cans made of the same paint I used to repaint the door. The door was done properly and ended up looking ace. The temporary paint I needed to apply to other areas to keep it weather-sure for a while was done with cans of the exact same paint and the best non 2k clearcoat cans I could find. They are in some ways surprisingly good considering the rapid speed at which I did them, but once you take a proper look, they're a completely different texture and no amount of flattening would fix that without cutting into the paint again and making it look even worse.

In my case they are at the sides of the car and on thin lengths of panel above a kink line. This helps to mask the difference a little because of the angles involved.





^ The way it bounces the light affects the colour match. The paint itself is actually an uncannily good match considering I didn't test it first. Sheer luck. But different textures of these parts, caught in certain light conditions, throws the colour back very differently. 99% of the time its a match. Catch the sun at the right angle though and as you can see in that picture, it suddenly looks like a darker tone.

For a bonnet, it's going to be very obvious I think, so I think you'd at least want to make it consistent by doing the whole thing, not a patch of it.

I'm assuming this isn't a car where you might be looking to take creative advantage of limitations by having a contrast colour or a matt finish or whatnot.

People say you shouldn't attempt to flatten down the texture of metallic paint, and at the risk of incurring the wrath of experts, I have a theory that it might be worth experimenting with this because others say they do it all the time and get good results. The rough texture comes from the accumulation of multiple layers of spitty nozzle spray required to get total colour coverage / opacity and 'tonal depth' (for want of a better phrase). By the time you've achieved that with rattle cans to buld up thickness, it's like orange peel. But if I had time I'd like to experiment with building that up, then flatting it back to a smoother surface, Scotchbriting it again, and THEN applying a colour correcting coat of the paint back over that flatter surface to finish. I think that would be a much smoother surface to then clearcoat onto, because you would have tackled the accumulation effect of many layers before adding the final colour surface.

If it doesn't work... not the end of the world... just do it again.

Right guys need some help on this one as it making me go mad, so I lacquered the panel and sanded it down for the removal of orange peel , I then uses g3 stage 1 and 2 compound and then stage 3 wax on it, all was well and smooth but now the paint looks Matt again and slightly rough, any idea what this could of been , would it need more lacqure or is the lacqure shrinking in the hot weather we are having I am confused all help greatly appreciated in advance.
