| Post subject: | painting my 21 SC - primer trouble |
I'm in the process of restoring my 21 SC. It's in my driveway(my only real option), disassembled down to hulls and crossbeams, upside down on saw horses, sanded, patched, sanded 4X, washed, rubbed with acetone, and I sprayed it with TS-780 Mono Epoxy Primer. http://www.bottompaintstore.com/mono-ep ... 12339.html I intend to paint it with this stuff (already purchased) when I sort out the primer mess. http://www.bottompaintstore.com/revolut ... 12347.html I used a HVLP sprayer and air compressor from Harbor Freight. I thinned it with acetone so it would spray. My problem is that the primer came out pretty dusty/gritty/chalky. I have found that there may be several potential causes, none of which do me any good now. How do I fix this? Can I just sand it with 220 grit? Something else? Do I have to sand it all off and start over? Just shoot me if that's the case. Might my paint come out the same way? It's mid-upper seventies today. My driveway is shaded. I don't think it's that humid today. Thanks for your advice, Tim |

Yah, knowing the cause now isn't much help. How easy is the sanding? You might get away with a quick sand (say 150 grit) then recoat with new primer thinned correctly with their recommended thinner instead of acetone. Then final sand before final paint. Others may have more experience, though. |
