We'll be back with you tomorrow morning from 04:30 BST for third practice and qualifying.
We'll be bringing an end to this broadcast shortly, but before we go, here's some of your F1/marriage puns.
Adrian Peckitt: With This Pit I Re-Tread, Whether on slicks or Full Wets
Shaun Bristow: I pronounce you Mansell and wife
Christopher Hill: You may now kiss the apex
Paul Bateman: Does any person here present know of any lawful brakepedalment why these two persons should not be joined in matrimony
Sterling efforts all round.
"It was better than Malaysia - I got to do the whole session so I'm happy," Hamilton told BBC Radio 5 live's Jennie Gow.
"Generally the car was feeling good and it was nice to get the running and the preparations. Hopefully that will stand me in good stead.
"The Ferraris look like they were as quick as they were in Malaysia. But hopefully we're quicker."

We asked you to vote on the most surprising of all the surprise race winners over the years - but is it a surprise who came up trumps?
Jenson Button was your pick, taking 37.8% of the vote for his amazing win at the Canadian GP in 2011. Olivier Panis was second and Pastor Maldonado third.
Time for Jenson to crack open another bottle of bubbly...

His best time, set on the soft tyre, was a 1:37.219 - around four tenths faster than the Ferrari of Kimi Raikkonen.
Red Bull's Daniel Ricciardo takes third, a second down on Hamilton, with the second Ferrari of Sebastian Vettel in fourth. Nico Rosberg is 1.2secs down on team-mate Hamilton, although he did not seem to get a clean lap on the softer - and quicker - Pirelli tyre.

The two were side by side through the first corner and then continued to battle through the next few turns before Rosberg got ahead.
Save something for Sunday lads.
Just on that bride and groom entry of a few moments ago. 'In sixth gear and in health'. Hmmmm, we're not sure.
We've come up with:

Holy Matra-mony
With this Hungaroring I thee wed

Daniil Kvyat just had an odd moment. With some flames and smoke coming from his left-rear brake, he was on a slow lap back to the pits but still carrying enough speed to run off track at the end of the long back straight.
The Red Bull bounced through a gravel trap and was almost at a stop when it kissed the crash barrier.
A soft impact but enough to remove the front wing.

Daniel Ricciardo, having spent much of FP2 in the garage due what Red Bull called "set-up tweaks", has gone third quickest on a 1:38.311.
Your top three with just under half an hour remaining is: Hamilton, Raikkonen, Ricciardo.
Image source, Getty ImagesWe've been asking all morning for your choices for F1's surprise race winners. We've tried to give you a taste of some of the standout candidates but it's far from an exhaustive list.
Even so, we've knuckled down to give you a list of eight race winners to choose from in a vote to find the most surprising winner.
We've gone for: Peter Gethin (1971 Italian GP), Vittorio Brambilla (1975 Austrian GP), Gilles Villeneuve (1981 Spanish GP), Olivier Panis (1996 Monaco GP), Johnny Herbert (1999 European GP), Sebastian Vettel (2008 Italian GP), Jenson Button (2011 Canadian GP), Pastor Maldonado (2012 Spanish GP). Apologies if your favourite is not listed.
The vote will close at the end of FP2

Steve Lank: For me it has to be Olivier Panis at Monaco in 1996 in a Ligier. What a legend!
Image source, Getty ImagesMoments before Felipe Massa's accident the Mercedes of Lewis Hamilton had clawed its way back to the top of the timesheets.
On the soft tyre, the reigning champion posted a 1:37.219 - four tenths quicker than Ferrari's Kimi Raikkonen, who also set his time on the soft.
Image source, AFPThe Williams has been cleared away and we're off again.
Felipe Massa is having a trying day in the Williams.
The Brazilian, who span in FP1, lost his car under braking for the hairpin at turn 14 and skewed left into the barriers, his tyres squealing in protest as he went.
The front wing of his car was taken off and he's off back to the paddock on the back of a scooter.
Kimi Raikkonen has been out on a set of the soft Pirelli tyre and set the quickest time of the day by some margin.
The Ferrari has posted a 1:37.662 - 1.4s faster than Hamilton's previous best, posted on the harder tyre.
Hamilton and Mercedes team-mate Nico Rosberg have gone out on the soft so a response should not be long in coming.
