i am also being told that the walltite needs to be covered but because its in a crawl space it doesnt need to be. Do i need to cover the dirt with 6 mill plastic or is that over kill.

I believe you don't need to cover with anything since the spray foam will act as the vapour barrier.

"Covering-it-up" may not be for a vapor barrier but for a fire barrier. Most foam insulations require a fire barrier between you and the foam if sprayed on an inside wall.

I had my crawlspace spray foamed last October. Both GNI (the company that did the job) and the energy auditor informed us that since the crawl space is not considered "living space" then a barrier did not need to be put over the foam.

6 mill plastic is good to help keep moisture from coming up out of the dirt. Do you store anything down there? If so, the plastic would be a good idea. It may be overkill but it just helps things stay neat and tidy plus you then don't have to worry about mold (remember, the spray foam will make your crawlspace virtually airtight so less air movement to help "dry" things out)

I'd recommend polyurethane Polarfoam 7300 over both.

I would have to disagree with you on that one, considering Walltite is the first medium density spray foam to receive the ECO trademark.
Walltite ECO just makes sense and purple it is.
