I recently applied a second coat to three of my wall art projects. I sanded each with 120 sandpaper. I wiped the dust with a rag then wiped with a tack cloth. The rag may have had alcohol or acetone on it a some time. It was dry when i used it to wipe the dust off. After applying the second coat craters began to appear on all three. I was creating circles and appeared to be pushing the resin away. Could the possible rag contamination be the cause. I am going to wait a few days and try again. Any suggestions is appreciated

Hi Mike,

What is the size of your surface and how much resin did you cast?

[Mike P]

12″ x 16″.
Could I possibly sand out the defects and spray polyurethane or laquer over the top to get a high gloss finish

I don’t know how you would be able to sand the defects and make them even enough for a coat of polyurethane. You can try the sanding, but I would recoat with another layer of resin.
