So I bought some headers of ebay that have quite a bit of surface rust, so my question is should I use some sanding discs that are for sanding parts like this or should I take them to a shop to be bead/sand blasted? If I used sanding discs what would the effect be on the metal if any? thx Ian:)

I would take them to a shop and have them beed blasted or even shot-peened!

You might consider sending them off to the following: http:// www.jet-hot.com In other words you can kill two birds with one stone so-to-speak...they will media blast them as part of the prep process to coat them with the jet-hot coating coating of your choice. Will last a long...long time after getting coated...make your engine compartment cooler too.....

be careful if you are sanding or sand blasting . Headers are not that thick and you dont want to remove any metal. I scuffed mine off by hand with some 220 paper knocking off the roughness of the rust . Spayed some metal ready on it and sprayed them whit header paint. I have a little over 3K on them and they still look like I just painted them. Gary

I went on that web site that you gave me webdawg1 and I summited the info. on my headers, if I do indeed get in done by them I will post some before and after pics. thx Ian
