8-347 Fast Surfacer
About the product
8-347 Fast Surfacer Grey can be used for small to medium repair work over multiple automotive substrates. The sanding surfacer can be applied directly on e-Coat primed parts and does not require an additional guide coat due to its glossy appearance after drying.
Mixing Ratio is 1 : 1 Surfacer : Thinner + 25% Hardener on volume
Potlife 15 minutes
Please note: The surfacer and thinner can be pre-mixed.
The hardener needs to be added to the spray mixture just before application, due to the limited pot life
