Any tips for spraying polyurethane paint? I have an ex SAS Polaris to repaint.

If you don't know what you're doing with Aliphatic Isocyanates or have the equipment to spray it safely, don't use it, stick with enamel. It's not really a DIY product. There's a reason why it has safety warnings plastered all over the vehicle. Cancers of the respiratory system or lymph glands, or skin irritation, or children with two heads can really spoil a great paint finish. You would want to have a real good reason why Enamel won't work for you.
That said, if you have the correct PPE, it sprays in exactly the same way as enamel. No particular difference in technique, just that the pot goes off in about 3hrs.

it really does sound nasty! even rubbing back seems to have its issues. i have done a fair bit of spraying of enamels and acrylics and use a full face respirator etc. so assume the same would work but will think a bit more on it. Thanks for the advise.

No, it won't. You need a disposable full-body Tyvek suit and clean-air-supplied full face mask (not just filter cartridges). The Isocyanates can also irritate and enter the body through the eyes and skin - full cover and dispose of afterwards.

And if you paint it at home in suburbia it will poison all your neighbours.
Must be done in an appropriate paint booth with full coverage air supplied paint suit and hood. Dont touch it unless you have access to the correct equipment.

In situations such as this one, it is always a good plan to Google the Material Safety Data Sheet (MSDS) first, before poisoning oneself!

I know the company I work for were fortunate enough to do the LRPV upgrades in 99-01 (I think that's when) and even with dedicated spray booths and professional spray shop were still unable to paint PUP. The vehicles were modified and the taken to a specialist. Very nasty stuff!
