ben1191 Posted June 27, 2014 Share Posted June 27, 2014 I've got a zs fiesta,there's some rust on the underside of the car that I want to sand down and then paint with that black paint seal stuff. What I wanna know is,do I just simply use a wire brush bit on my sander,or do I need to use certain grit sandpapers? Anyone tell me or show me a link with a good guide,much appreciated.

stef123 Posted June 28, 2014 Share Posted June 28, 2014 Can you show us some pics of where the rust is and the extent of it? Quote Link to comment Share on other sites More sharing options...
karlos1987 Posted June 28, 2014 Share Posted June 28, 2014 If it's just surface rust the literally sand it all off. Do not leave 1 spec on there as it will come back very quickly. Then paint it with the black sealant paint. However if it's not surface rust and goes through ( try stabbing it with a screwdriver) then it will be a welding job.

ben1191 Posted June 28, 2014 Author Share Posted June 28, 2014 It's just surface,it's not even that bad as the cars very clean,just want it spotless really. Sent from my iPhone using Ford OC Quote Link to comment Share on other sites More sharing options...
karlos1987 Posted June 28, 2014 Share Posted June 28, 2014 Then just sand it down and slap on the paint mate. Sent from my C5303 using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...

jeebowhite Posted June 28, 2014 Share Posted June 28, 2014 Use an intense sandpaper (the lower the number the better - 400 grit for example) and treat it all up. then, if you have KRUST - you can then wipe down all the area that you just sanded with KRUST and leave it to dry. Once its dry, then you can use the sealant Quote Link to comment Share on other sites More sharing options...
ben1191 Posted July 1, 2014 Author Share Posted July 1, 2014 Is this thick enough or will it need a second coat? Quote Link to comment Share on other sites More sharing options...
karlos1987 Posted July 1, 2014 Share Posted July 1, 2014 I'd go with a second coat. Sent from my C5303 using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted July 2, 2014 Share Posted July 2, 2014 I would suggest going with a triple layer the way its applying. Quote Link to comment Share on other sites More sharing options...
ben1191 Posted July 2, 2014 Author Share Posted July 2, 2014 The camera flash made it look thinner than it is,but I will put a thick second layer on it,didn't have the best of brushes to apply it either lol. cars lowered so even on the jack the vision wasn't that great.
