Works like it’s supposed to!
Works great, doesn’t clog up your paper like regular spray paint would. One can was depleted after covering this entire Mustang so you can see the mileage you get out of one can. Will buy again.

Highly recommended for eliminating uneven surfaces to which a smoothing medium has been applied.
A really useful product for eliminating the irregularities in uneven surfaces to which a smoothing medium has been applied. As you sand the surface the black guide coat is removed first from the high spots thereby revealing the low spots which may be addressed by additional sanding or the application of more smoothing medium. Guide coat is formulated not to clog your abrasive medium, which speeds up the process and produces a better finish.

Guide coat
A must for doing body work. I tried four local parts stores and three of them didn't know what guide coat even was.

Lousy spray pattern
The nozzle on these have a terrible pattern, guide coat is supposed to go on thin and even, this comes out in a small concentrated glob.
