hey guys, i need to clean my tank internally
wondering if anybody knows what chemical rust remover i could use
ive found 1 product POR 15 but is there any alternative
would be appreciated if anyone can help me :D

Pretty sure you're along the right lines. I've complete faith in anything Frost Restorers stock, and that's what they've chosen:

I ran a POR15 kit through my NC30 a month ago and it did a great job. Just stick to the instructions like glue - especially the part about drying out the tank after cleaning it.

Lot of people recommend petseal, but it no-one would ship it overseas, but is worth a look if you are in the UK

Use the POR15 you won't get better.

well that solves it POR15 it is :), i got it from that frost's website also mate :) will it clean out all my tank proper, cause ive got a lot of crap in there, keep getting in my carbs have to keep cleaning them, ive gone through 3 fuel filters in about 5- 6 months =/ so if i clean it proper etc, wont need it lol

I've used their marine clean before and it's pretty potent stuff. It should do the trick.

sorry the reply is late, got there tank internal kit pretty much!? did the job, tank is like new again :D
hehe also become a proud owner of a Honda RVF400 =D
