Silicones (Fish eyes) in fresh painting.

[gus]

Anyone painting runs the risk of having Silicones spoil their painting finish. There is an easy way way of ensuring that your surface for painting is free of Silicones. Lots of various methods and dubious products available on the net but the one sure way I have learned from my past life in a car body shop, is to wipe down the surface with a rag generously soaked in petrol - seems to do the trick. Take the necessary precautions with the petrol of course.
I would be interested in any feedback.

Many thanks for that, my interest is more in classic cars. Unfortunately many people just buy what is advertised as "good" car polish or waxes, with no regard to whether or not it contains silicone, and most I'm afraid do. I'll certainly give it a go.

I've used acetone in the past which also seems to work and does not leave any oily deposits which petrol is prone to do.

I bought some wax to put on my hull from a chandler last spring. I used a bit around the cockpit but fortunately I read the label before putting it on the hull - it contains silicone. Although some people would say it doesn't matter, I would like to be able to say that silicone has never been put on my mostly white hull.

Acetone is fine if you are coating onto a surface that will not be effected by acetone. Repainting house woodwork where there has been the liberal use of silicon polish will make you appreciate petrol, which in any case mixes with traditional house paint.

Same here.

In extreme cases i have used anti-silicone additive with car resprays. I have had the very odd panel where nothing short of stripping back to bare metal will stop it.

Silicone can be the worst of all enemies. It creeps and creeps and is really hard to eliminate. Thanks for the tip about petrol.

I've used a product called 'No Nonsense' sealant remover ( £1.99 for 100ml) from Screwfix to remove Silicone when doing some work on the house kitchen, works very well , comes in a pot with a brush,

Then you were extremely lucky. Usually no amount of stripping with abrasives or solvents will remove it. Tenacious stuff. At least thats my experience.

Its not always on the label either, at least not in plain English. I usuually contact the manufacturer to be sure. Hate the stuff - banned on the boat, in the garage and in the house.

Two different things... silicone being discussed here is the ingredient in polishes and sprays... the sealant is different, however I agree the removers work well when resealing something

Thanks for pointing that out, my misunderstanding.
