1 X S2031 EXTRA FAST HARDENER 1LTR. S2031 EXTRA Fast Hardener. It is suitable for spot repairs to full panel applications which can be air dried, low baked or I.R. cured. High quality isocyanate hardeners for use with 2K acrylic coatings.
I have white and black versions of this primer and mix it together to give the shade I want.
An excellent high build primer and they use the same hardener as the Upol clear coats which is very handy and cuts down on wastage if you not using it all the time.
Gives really quick drying times with the fast or extra fast hardener but does still give reasonably good life in the gun, highly recommended
