Yep water based additives only from new champ onwards to help track life span basically.

The best water based additive for foam is jack the gripper tc2 we believe but lrp carpet works also and is easy. We have all gone from using cs to lrp and it's fine no problems with the foam changing from additive to additive but we did clean the foams with brake cleaner (spray some on cloth a d wipe around). This helped pull out some the oil residue.

Gloucester are having this problem due to the larger number of gt12's on such a small track so regular. If you think we have around 30 cars doing 30 laps each, each round.... That's alot of times foam goes across the same patch of carpet laying in the oil making it so black.

If you take other clubs with maybe 15 gt12 doing 25 laps? That's less then half what we getting. I've also been told brca 12th events also having same problem and are looking at doing the same thing, worlds and euro events have been spoilt by the carpet turning Into a slime but the afternoon so it's a well know problem at the min.

The foams seem not to mind switching from oil to water but we do clean them in between.

Additive is only £9 for 125ml (best value additive out there) which isn't alot to try save the club thousands in new carpet.

Guys, can you please confirm that this is the fluid being used:

If so I'll get some. Otherwise, let's see some links to the right stuff. Cheers.

Yep that's the one. I think that is the one Mark has been using, and seems to be one of the best.

or there is a newer option- LRP 3

Not sure if there is much difference but if there is an advantage I would say the LRP 3 is slightly better on foams (if at all)

Sweet, I got the 3 version of the stuff.
Hopefully it goes well on trizzack.

Ok after running the LRP 3 this week I found it to be the best I have ever used. Didn't seem like the grip level reduced at all over a run, which it used to a lot with the CS I was using before. Don't think you can go far wrong with this stuff!

Spider Grip is being trialed at the Chesterfield Summer Shoot Outs on May 19th.

Costs more but it's a bigger tin ;)

Just to make it clear spider grip green is oil based so will NOT be allowed at Gloucester
