Paint shrivels after recoat

Hello everyone. I am new to the sight and haven't had any luck finding a post with the same problem I am having. I am painting an old steel bicycle with acrylic enamel paint by rustoleum, I primer, seal, base coat, wet sand the base coat with 600, then when I reapply the base, the paint starts to get these raised veins all over my project. I have no idea what is causing this. I wait about 30 minute after wet sanding before recoat. I hope someone could shed some light on this for me. Thank you.

Saul

Too much product too soon.. You may need 24 hours of flash time before recoating with that product..

The primer I let sit for 12 hours. the sealer I let sit for 1 hour before basecoat. the basecoat was left 6 hours before wet sanding and recoat. Should I allow a full 24 hours in between stages to ensure that the "veins" do not appear? Thank you for the quick reply.

Acryic Enamel doesn't require a clear coat. Is this an aerosol product? If so, you should allow at least 24 hours before trying to sand and reocat if there is a problem with the finish. Be sure to read the tech sheet or instructions on the can, as each manufacturer has different spec on how to handle problems.

Would it be alright if I do add additional clear coat to the acrylic enamel? This is an aerosol product. The can falls short of instructions but I will comb the net for a more specific tech sheet..

Yes it should be fine to use a clear coat over the enamel, but make sure it is a urethane or enamel based clear coat. If you spray a lacquer based product over the enamel it will look like you used paint remover. There should be instructions on the can that tell recoat times, dry to touch times, etc. You should not attempt to sand and recoat it before the recommended recoat time.

DON'T SAND IT OR SCUFF, not unless its months old. It looks dry & feels dry but under neath the top coat its still gassing out Rustoleum takes a long time to set up, like weeks. You can respray it as much as you want, just don't sand on freshly painted Rustoleum an expect another coat of paint on top of that to stay.
