Just got back from a little evening run out in the pickup.
I stopped to get some fuel and managed to spill some E10 down my 3 week old cellulose paintwork with disappointing results.
It immediately softened the paint and took the shine off.
Has anyone spilt E10 over older paint? Any effect?
Mike

I can only guess (and stand to be corrected) that as fuel becomes more alcohol based then it may act like a solvent on certain paints with the results you describe?

I am somewhat dismayed that an E10 spill onto cellulose paintwork can have this effect. It is making me wonder whether to paint my TC with it ...or have the car sprayed in 2 pack. My dilemma is that I have already bought the cellulose paint. I am also way over budget already and haven't factored in the cost of an outside paint job. Shocked

You could just use 2k for the clear coat?

An interesting suggestion... but the reason I opted for cellulose was because it is safer to use at home (with a face mask) and save the cost of a body shop.

Isn't 2K carcinogenic?

I believe so.

Regarding petrol and paint?
Before blaming E10 [which might not contain 10% ethanol at all, given the supply issues with ethanol currently?]....why not try testing one's paint with petrols, first?
It may be, it's the petrol itself, regardless of its ethanol content?

Could the issue have arisen because the paint simply wasn't 'hard' enough after a re-paint?

All these are questions I'd be trying to find answers to, before blaming E10.....

Good point Ashley. I regret to say but I do tend to jump to conclusions... but Miken has got a problem which ever way you look at it.

Rotten luck. Sad

The main safety issue with 2K is the Isocyanate used in the hardener, it can kill or trigger respiratory problems, however there are Non Isocyanate hardeners available these days:

It says drying times are much longer. Without having a dedicated spay booth it probably would not be suitable.

I rely on a fast drying paint because the longer it is left wet, the more chance of a foreign body landing on it which in warmer, dryer weather is a real issue.

A vinyl wrap often crosses my mind when it comes to the 2CV in particular. No idea if it's possible on a car that has sticky-out bits like rain gutters which modern cars do not have. I've no doubt it'll be easier to wrap the pre-war Minor which has a much simpler, flatter bodywork, but the effect might not suit a vintage car Laughing

I used to know a not quite honest dealer. He would respray cheap cars with Dulux thinned with petrol, it looked fine until it had petrol drips on it.
