I am really happy with the final result. Here's the recipe: - remove interior sound insulation, - remove undercar rubber coating, - sanblast interior, undercar, engine bay - clean all the left sand from closed body chambers. - apply marine clean, - apply metalprep, - apply two coats of POR-15, - apply POR-15 prime, - apply four coats of sound insullation. Voila! It took me 2.5 month, working 8 hours a day to do this. Would I like to do this? - Never. :)
