How much sanding is required on irregular surfaces? Do all surfaces need to be dull before you apply the next coa
The project I am working on is not 100% flat. I have applied one coat of the Penetrating epoxy Resin Sealer. There are a number of low spots and other irregular areas. Do all of these low spots need to be sanded before the second coat is applied? Many of the low spots are smaller than a small fingernail.
