I find that CG CW&G is a little to strong the foam gun application. For me I only use it as bucket wash or for when I am stripping an LSP. I find the longer it dwells the more it "strips" the LSP, no matter what Dilution I use it at.
Yeah, perhaps I'll use it in the lance (Wolfgang) to only strip LSP, I'd rather be safe than sorry. I just washed my white Fit, I must say, it's one hell of a soap. Should last me a long time too.
