Re: Polyester putty
lesley,
brand of 2K putty is less important i think... For the moment, I use 'soudal', but have used other brands previously & simultaneously. Always a 'soft' version, as the hard ones are really too hard to sand by hand.
TIP: try using a sharp knife to remove excess while putty starts to cure: you'll have few minutes to really sculpt the putty, and thus save time sanding. Be careful and cut away(!!) from edges etc, as otherwise stuff might brake loose.
Also, i sand plastic with P240 and add a plastic primer before adding putty, otherwise putty will tend to come loose very easily. Brand of plastic primer = motip (spraycan)
I think the motip filler is an interesting product: comes in spraycan, and can stand both 1K and 2K laquers/fillers on top... Very easy to sand, but not strong of course. I use it on puttied surfaces as a layer before applying 2K base coat so all scratches & stuff are easily seen/filled/sanded out
The 2K base coat is: acryl-füller, 4 to 1, from airo. For sale in specialized car paint shops. Will cure hard, but still little flex, so not too brittle.
