dry sand
the intake has a coating on it which makes it really sloppy..mine does at least..its a grey weather resistant coat..anyway
i would go 80,180,400, 800 1200,,thats what i do anyway,,then use the compound...thats on open pieces..and a air r/angle ///the cracks anf crevices you need to use the gritty cmpunds,they are used on a wheel or drill,like liquid sandpaper,,there is different grits.again verry messy..the tripoli is verry hard to use to remove scratches from 400 unless your real nice w/polishing and have alot of time........believe that!!after 1200 a white compound for a tiny bit any newbie can do...then some mothers chrome polish and your in..DO NOT think your gonna polish something by hand!! its possible but you would rather push your car 10 miles w/no shoes on..
practice on a small piece and when you get the mirror shine youll get an idea of how long an intake is gonna take...i estimate an intake from 94/95 to be about 20hrs of labor ,,experienced,,,40-45 newbie,,if you dont own material,,they will cost around 100! at least!!it cost me over 250 for sanding disks alone, hook and loop discs...29-37$ a box of 100,then u need a buffer wheel 10$sears they sell 3 wheels and 5 huge bars of compound,white,tripolired,rouge,and ?brown?<<good deal...
you will need a hook loop tool that holds the paper.called a mandrel.
or....you could get a 3m scocthchbrite mandrel and use the scothbrite disks ,,they are cheaper,last longer,,easier to get into grooves,,they come in 4 different colors and grits.vry cours,course,fine,ultra fine,,,,,,ultra fine is 180 grit ..then i go to paper.they also have kits u can get from a search under polishing kits...cheaper tooo...and they sell nickel,chrome,aluminum,silver,gold plating kits...from 150-1000$ which work awsome as long as you dont need to dip anything bigger than a 20 gallon pale they include..
this book is finished good luck guys..ill be back
