Did you wetsand the color coat before clearcoating?


I STILL believe it's a mistake to not wetsand the basecoat before 
clear.    The clearcoat needs some tooth to grip if it's of 
dissimilar compounds than the base coat and the solvents in the cat 
paints simply don't grab onto lacquer like the lacquer clears easily 
do.   Seems rational that a good wetsand with thousand+ grit would be 
the way to go if you wanted a non-lacquer clear to stick to a lacquer base.


All the examples of that combo I ever saw that were peeling showed a 
glossy lacquer basecoat under the peeling clear, mostly on those 
motorcycles I mentioned in an earlier post.
