pinholes

depending on the size of your project you can also use a Resin and Body filler mixture one to one ratio works good depending on the thickness of the resin you are using . you want to make a mixture that you can pour onto the project . thin enough for it to cover it like a the red stuff on a candy apple , it will fill the pin holes and leave a nice surface for final sanding . just add  MEKP to it like the mixture was all resin . be aware that if you dont want the mixture to get all around the project like the speaker ring and sides and back  you may want to "paint " it on with a brush  where the pin holes are located ., then you can just fill the holes and sand those spots only .

small project like pods i pour,  large sub enclosures i brush only where needed . if you pour it,  it will be al lille messy and will leave drips of the mixture on the bottom of the project
