Realize this is an old thread but there's been a lot of new advancements in clear over your side of the world

Ultra-FIllŪ DTM Isocyanate (ISO)-Free Primer/Surfacer
Premium Ultra-Fill HS is a Direct-to-Metal (DTM) ISO-Free Primer Surfacers NP75/NP74W are free of lead and chromate hazards.
Direct-to-Metal (DTM) ISO-Free Primer Surfacers free of lead and chromate hazards. As high build surfacers, with excellent gloss holdout and sanding characteristics, NP75 / NP74W / NP76 can be used in Collision and Fleet markets. NP75 / NP74W / NP76 provide excellent bare metal adhesion and corrosion protection without the need of an etch primer and meet National Rule VOC regulations of 4.6 Ibs/gal.
Why do we need Isocyanate free coatings?
Research into a polyurethane network without exposing the applicator to isocyanates has also been recently developed.
Cyclic carbamates have been found to convert to aliphatic polyurethane systems through reacting them with polyamines, thereby eliminating the potential of isocyanate exposure to the applicator. One of the drawbacks to this type of approach is the complete overhaul of chemistry and starting materials, which does not result in a network with original chemical characteristics and properties of a standard polyurethane system.
