You're input in painting matters are always very informative Dave. I'm a recent user of the Mr Surfacer 1500 and so far really like it over the Stynylrez. I aways got a grainyess when spraying it. Not so with the Mr Surfacer. I'm doing a black paint job right now. Very smooth finish. I did a spoon test spraying clear directly over the 1500 and wow, it really came out nice.
Thanks for your input 😊
