GAZRNR Posted March 7, 2004 Share Posted March 7, 2004 A question for the professional painters. I am painting my car in at home in a "home made booth" that does a pretty decent job keeping the dirt & debris out. Last fall I preped the engine bay, used etching primer on the bare spots, 2 coats acylic primer-surfacer and then the base & clear coats per the direction from Sherwin-Williams. The finished job came out much better than expected given it was my 1st effort at spraying automotive paint. After spraying the primer, letting it dry, then wet sanding, cleaning up the work area & car to be ready to spray base & clear all in a 24-36 hour period took all the fun out of the process. For discussion, can I prime the car this weekend, wet sand it over the following 5 days, then come back on the following weekend with the area prepard to spray base & clear and have the paints work together properly or will to much curing have occured on the primer? The primer will be on the car 6-7 days before base & clear will be applied. I have the material data sheets for the products I am using but maximum number of hours/days between primer & base is not stated. Thanks, Rusty Quote Link to comment Share on other sites More sharing options...
BIGJIM Posted March 7, 2004 Share Posted March 7, 2004 you will have no problems...6 days is pleanty of time. i have final painted over fresh primer within 2 days of spraying it. when you start your final block sanding you will be able to tell if your primer is cured right away!

GAZRNR Posted March 7, 2004 Author Share Posted March 7, 2004 Thanks Jim, The Sherwin-Williams automotive paint people told me that the paint ALL primer, base & clear cure togther to create that tough as nails (hard) finish. Is waiting 6 days to spray base & clear going to affect the paints ability to bond on to the primer? Quote Link to comment Share on other sites More sharing options...
BIGJIM Posted March 8, 2004 Share Posted March 8, 2004 not at all. as long as you give it a good 400 sanding (i wet sand with 400 before final paint) everything will be fine. try to sand it the day before or the actual day you plan to paint. good luck man, hope it turns out sweet!

love-my-V8-280Z Posted March 12, 2004 Share Posted March 12, 2004 Well I have a question, years ago peope used Laquer paint, than moved to Arcrlic, not its urathane know as 2 part, or base coat clear coat. First I have been told you don't want to let Arcrlic primer sit for long periods of time as it will absorb mosture. The Urathane don't do this and can sit in primer for years. One I did not think you could paint urathane over arcrlic?? They do make a urathane primer as that is what I used on my car over a etching primer. Oh and the one of the difference between is Laquer and urathane is not that the urathane is harded but I would say softer... My boss painted his truck with laquer and in one year he had a crap load of chips becuse he lived on a gravel road. Mostly on the lower front of the truck. Anyway he repainted it with 2 part and in 3 years don't have any stone chips, he told me he is amazed with the difference Quote Link to comment Share on other sites More sharing options...
