I like 3M Platinum in gallon can. Goes on smooth, sands easily, some pinholes but I think all fillers will do that at times. Be aware, just cause it comes in a gallon can doesn’t mean u get a full gallon. More like 80% of a gallon. Don’t know why 3M does that??
I guess it like potato chip bags get smaller and smaller but price remains the same! and ice cream too.
Have a good Sunday all
