Ralph,

Mine wasn't BullDog brand....Probably the same type that Steve Collins used. I remember the quart can having a picture of a Corvette on it. It worked well but as you said it is messy and you end up sanding some spots anyway.

Luis,

Be carefull not to get too aggessive with the razor blades...You can weaken the fiberglass if you put too much pressure on it. Curved areas were very easy....The flat areas gave me the most trouble.
