QOTW #23 – How do I detect + deal with paint blistering on my Aston Martin?

Back to videos

Welcome to BamfordRose and another question of the week. This week it’s paint blistering or rather the dreaded Aston paint blister. This has affected cars since 04 DB9, 05 V8 and on current production stuff. Well, at least what I know to be the Ford generation, so pre-Mercedes technology. DB11, new V8 Vantage, I don’t know if those cars suffer the same problem. But certainly, the last of the run Ford era cars I’ve heard of paint blistering on very new cars. So, it’s all that range of cars and they’ve had years to get rid of this problem but it just seems to plague them and they can’t get rid of it.

As you can see from the pictures of the silver V12 Vantage, this is a typical early start of what is called corrosion paint blistering, affectionately known here as the pizza. As it gets bigger, it just spreads out and blisters and looks like a bit of a pizza. You can see the door handles. This is another common area.

So, the paint blistering happens on roof edges, door handles, top of the doors, around the rear quarter by the glass, and the boot lid of a V8. There are some common places where this happens. I’ve heard the factory excuse this problem for many different reasons. Oh! Its corrosion in the primer, oh! It’s something in the base coat. But if that was true, why does it never happen in the center of the roof or the center of the bonnet, it only ever happens on edges and in the common places.

So, rather than the paint curing process, you’ve got to put this down to contamination, cleanliness issues during painting. It can’t be anything else. For years, the factory have not covered this and ten-year anti-corrosion policy because they center got out on anti-corrosion policy not applying to paint. Now as their reputation gets dragged through the mud a bit with this problem like rear lamps, LEDs blown on front headlamps, this is very annoying to have this problem happen to your car. And I have heard recently of dealers part funding or entirely funding some corrosion repairs.

If it’s on a couple of panels, it’s not so bad. You can do a little bit of a localized base coat and then lacquer of the whole panel, so it’s not a big problem to get rid of, you know, I’m into paint the whole car, unless and I’ve seen this on a couple of cars it’s very unfortunate, you’ve literally got paint corrosion on all of the panels and then it is a complete respray.

What to do if you buy, run your finger all around the edges of each panel, the door, the bonnet. Lift the bonnet up, have a look on the end underside because on the bonnet it starts from the underside lid and then works its way over the top. So, run your finger around the car, all around the edges very lightly, and on your fingertips, you’ll start to feel a little bit of a rougher surface where it’s bubbled. And then at least the point of purchase if you feel or see a little bit corrosion on the bottom on the door, an area where you wouldn’t normally look, you’ve only found this because you’ve run your fingers around it, then at least you get some money out of the deal and the repair isn’t that painful.

Unfortunately, if you own the car and it starts paint blistering then repair is the only course of action. And like this silver V12 Vantage, that’s been left a little bit too long. And unfortunately, that’s going to need the screen out now to properly get rid of corrosion which turns it into a much bigger job. So, it is best to attack the corrosion as soon as you see it. Maybe if you see a little bit of corrosion in one place, you know, wait six months, keep a close eye on all the other panels and fingertips, then attack corrosion in one go but the key is to sort it out before it spreads. As I say, even in the case of V12, it’s got a much bigger repair now because it’s been left for a long time. All I can say is that on all the cars that we’ve painted that have had corrosion, the corrosion has never come back, so again this sort of suggests that it was contamination in original paint.
