I've seen this on eBay. Spray putty filler. What's it for then? Is it a filler primer like the halfords stuff in aerosols or is it more like body filler or somewhere in between?

My body panels are coming on but I suspect that when I spray on the primer, it will reveal a whole lot more prep work. Am I best going for this stuff or just a normal high build primer?

I suspect its the same thing, being a creature of habit just high build I recon. This is probally more suited to molding in chav box arches on saxo's !

I think the putty is thicker than high build primer you will probably need a compressor for professional use rather than a 3hp 7cfm type
