The pic below shows some marks which seem to be getting more prominent on the bonnet of my 1988 morgan. I first noticed a couple of them last summer, I suspect that on a warm day the car got rained on and then stood in bright sun, so the beaded rain water evaporated rather than running off. The whitish marks are completely smooth, there is so significant change in the glossiness of the paint, just the colour change

I have tentatively used polish on a couple but no real help. As the paint is 23 years old and being a morgan has probably spent many years being polished rather than driven, I am reticent to go too mad with abrasives.

Since the first few developed the car has been waxed a couple of times and over the year the marks have become a bit more widespread.

Whats the best remedy for this, I have been intending to try one of the cleansing products, such as the autoglym high def cleaner that goes with their wax, but would claying be helpful too or instead?

Unfortunately my time is a bit limited these days so I am wondering if it might be better to treat the car to a professional detail.
Anyway, heres the pic, tips welcomed.

At that age its single stage red (unless its been repainted in 2k with a clear coat), and some of those marks will be water spotting plus a bit of paint oxidation (uv rays on the red paint).

Wash, clay, machine correction.

Have your paintwork measurements taken before thinking of correction so you know how much paint is on the panels, just to be on the safe side.

You might find something like Carlack 68 (by hand) might be enough to solve this.

Or have a look around your area for a detailer who will come out, access and give a quote.

cheers, there is a well respected (at least on the north east forum) who is not too far away from me, so i'll get a bit of professional help with this I think.

As said, ask him to measure, sometimes with low readings its better to improve rather than correct if its original paint.

Could you keep the thread updated with findings and results please, mainly because I like your car.

Cheers.

not looking bad for 23 year old paint. there are a couple of slight marks that didn't fully resolve, but the whole car is red now rather than pinky. The fact that the guys cleaned my wires as well, made the project pretty cost effective too - saved me a whole weekend of pain....
