Sam Tordoff this time led an MG one-two ahead of Jason Plato at Donington Park as the Triple Eight team continue to dominate on an incident strewn day.
Tordoff, as Plato did in race one, led from lights to flag as the young MG man immediately got the better of his elder team mate by passing him around the outside into turn 1.
This time the starting conditions could be classed as fully wet and the slippery surface soon triggered a safety car at the expense of BTCC Alain Menu who lost control of his BMR VW, miraculously missing the oncoming pack as his Chrome Edition Restart Racing machine span across the track.
The field briefly reengaged into race mode before being once again restrained into safety car formation, this time enforced following the violent crash involving Toyota's James Cole and Audi's Rob Holland.
None of this however was able to stop the march of the MG's as Plato's second position puts him into the championship ascendency.
Gordon Shedden claimed the factory Honda's first podium of the day after prevailing for the final step on the rostrum ahead of Pirtek's Jordan.
Jordan had clawed his way back into third following a clumsy start but slid off the circuit handing the position to the Scotsman in the process while having to defend from Matt Neal behind who eventually settled for fifth.
Colin Turkington was the top BMW in sixth as the eBay Motors cars seemed to struggle in the tricky conditions.
His eBay team mate Rob Collard saw his race cut short after spectacularly spinning out of the order.
Mat Jackson was the top Airwaves driver in seventh making a significant improvement from a disappointing 14th in race one.
BMR's Aron Smith had a steady drive to eighth in front of the rejuvenated Dave Newsham in ninth.
Tom Ingram produced another consistent performance to finish where he started in tenth position.
