Some more polishing by hand and it made a real difference.
Also, went on a short trip last weekend and couldn't refuse to test the suspension and have a spirited driving on probably the biggest jump here in Lithuania.
You can't see the thing in the above pic, but here it is and it's called grandma's hill
(type "bobutes kalnelis" in google to see more photos). Many oil pans are damaged here. It was enough to go at around 80km/h and make the rear wheels spin. I woudn't call it a jump, but that really gave some adrenaline 
Next time I must take a GoPro with me.
