Afternoon all,

The paint is flaking off one of my rear parking sensors (the black one in the valence rather than a car-colour painted one if that makes sense).

AM highlighted this at the MOT and offered to replace the sensor for £350 for me. I have declined.

I would rather give it a dusting of spray paint since it is unsightly.

Any ideas what colour it to use? It is black, but which one... I would mask up and spray it in place, rear bumper removal is a large job (probably why the high replacement cost from AM).

Photo coming when the car returns from AM.

Thanks.

Not my area of expertise, but I was told by a repairer once that parking sensors should not be painted at all. It may blend in well with the rest of the body, but the paint will block the signal.

In principle this is correct. I fitted a set of brand new sensors to the rear of a Porsche a few years ago and they came with a set of plastic rings that you placed in the circular groove around the central disc before applying paint and then removed them afterwards. However, the rear bumper on my daily driver has now been repainted twice (not my fault, honest) without any protection to the sensors and they all work fine.

I have also replaced one of the rear sensors on the Aston, painting it to match the body colour without using a protective ring and it has been absolutely fine for four years now. As long as you do not put too much paint over them, so that the gap between the central disc and the outer casing of the sensor is not solid with paint, it should be okay.

A lot of the advice around additional paint is very manufacturer specific and generation specific.

For example any recent modern volvo, good lucky as essentially you cannot repaint any part of the bumpers without impact on some element of tech.

I would seek out someone with access to AM's internal documentation just to make sure your own car is okay.

I am in a similar thought wave with my current gen Vantage as it is getting some paint on the rear and has blind spot monitoring which is in the rear bumper.

After owning many Jaguars where these especially on the X350 are a known weakness , doing it yourself as you suggest is easily within your capabilities . They always come unpainted and in my experience coloured
Black , plenty on EBay and they aren’t necessarily Aston specific . A good finish is easily obtainable using a rattle can , I never bothered painting the flexi rings as in the Jaguars case they were largely invisible once in situ

The black paint flaked off my rear bumper sensors last year. Whilst i was having the powerkit fitted the bumper has to come off anyway so my friendly tech who was doing the job resprayed the sensors.

From what he said it was a common enough problem and I belive he just used a fairly std can of black spray paint. They looked like new again once he had done it.

Thanks all.

The sensor works and obvs what I don’t want to do is kill it with paint. I painted some on a golf (silver) 20 years ago and they were fine.

I will spray some matt black on a random bit of plastic and hold it next to the sensor, if it is terrible I will buy another brand.

If you can bear the thought of an aftermarket Land Rover part being fitted to your AM and your sensor is a suitable size, then there is an inexpensive alternative.

Thank you.

I will give those a try! We do love PowerfulUK, especially their videos. My new Defender has much of their stuff screwed to it :-)

I have just replaced mine for the same reason. They are the same as some range rovers and Volvos. Made by valeo and can be purchased for about £12.95each on eBay. Seatch Valeo PART NO: AH42-15K859-AB
