Hello All,



Last week the business next to ours had their roof repaired. About a dozen cars in our lot have a fine coating of tar spray now...... Just enough to make the finish feel like sand paper.



Looks like there will be no help from the roofer or business owner but that`s another story.



My question is, would this be the time/excuse for me to finally buy a Porter Cable 7424?



If so, could someone give me a basic step by step so I don`t screw it up trying to remove this junk?



Thanks,



Eric
