has been applied and most preferably after two such layers have been applied the squeegee 60 is utilized by passing along arrow a of fig4 to press the ptmeg or similar material into the outside of the wood core 20 to form a tight bond 35 the squeegee 60 runs longitudinally along arrow a and then for convenience the entire wood core 20 can be rotated about arrow b before further passage of the squeegee along arrow a until all surfaces of the wood core 20 have had the squeegee 60 applied thereto to press a layer of the outer coating 30 into the outside of the wood core 20 the process of coating is then continued with the spray head 50 with both longitudinal motion of the spray head 50 along arrow a of fig4 interposed by rotation of the wood core 20 about arrow b of fig4 to apply successive additional layers of ptmeg or similar material after about ten layers and most preferably twelve layers in total have been applied all of the desired ptmeg or similar material has been applied to form the outer coating 30 a final finish of the outer surface 38 is prepared by running the squeegee 60 over the outer surface 38 once more to provide a desired surface finish most preferably this surface finish is a smooth surface finish free of bubbles or other imperfections the coated piling 10 is complete and can be allowed to cool and finally cure if multiple wood cores 20 are to be coated the spray head 50 can be kept active by bringing a new wood core 20 located upon separate carriers 40 into position for treatment of a new wood core.
