Here are the links from where I ordered it. TCP Global is where I got all my body work supplies, paint, primer, etc... The undercoating is around $25 a qt and the gun is around $100. I did my under-body with three cans and if you are doing the trunk too I would say four cans total. Let me know if you need more info.
3M Shutz.....is this a commercially-available product in an aerosol bomb? If so, what's it going for per can (I need to do trunk and complete underside)?
