One or Two Coats of Primer
Hi Guys - for you long time scale modelers, I have a question and need for understanding application of primer. Is it written somewhere that you spray on one coat of primer, then practically sand it all off, then spray on another coat of primer, and sand again prior to applying color? Is a second coat of primer really necessary? Is a 2nd coat of primer only necessary after filling dings, tiny holes, blemishes, shop rash, etc. or can you simply go ahead and spray on a base coat over epoxy fillers, balsa, bondo? Many thanks.
