ok, i know to lap from all the researching i have done. but I dont know where the cheapest palce for sandpaper is. i been looking around and more sites have a min requrement of how much you have to buy. I just need 3-4 sheetes of each

400, 600, 800, 1000, 1500, and 2000 grit that are for metal and are water proof. i cant find these in stores where i am, so internet is my only hope. i been searching many places but still no good enough deal. please help!

Do you not have a local building shop or hobby shop? If you were in the UK I would surgest B&Q, Whicks, Skrewfix, or hobby craft. Are any of those in the US too?

After a quick google, I found these. I think it's what your looking for, however I'm not 100%sure.

i can find the grit and type just fine. its the price that i dont like. many sites the net worth is only 25 cents per sheet, but they make you buy in huge quanities. i dont have the kind of money to spend on places where i can buy 1 sheet at a time for $1.50, but i also cant afford 25 cents per sheet but have to oerder 25 or more of just 1 of the many Grit i need and then add shipping to it all.

oh, ok, Thats the sort of thing you need to go to your local hobby craft shop, or car parts shop, they could well sell them in small quantities, and if not, you might be able to purswade them to sell you just a few sheets.

Great guide which helped me, Also if i were you i wouldn't be thinking of how much the sand paper is going to cost because if you go with cheap sand paper and it doesn't do the job properly that could potentially damage and increase temps if not ruin the HS surface all together.
