Dr. Deltron-just the person I need.How can you tell if a defect will show thru paint.I just steel-wool-600 grit papered out a rust spot on a steel framed bike.There is just a hint-barely a pinpoint-of the original defect left.How can I tell if the defect will or won't show thru new paint?
I dabbed on some spray enamel that I "caught" on a piece of foil.It didn't show after a day,and 2 dab coats.I have my doubts about this method of testing.
Does the surface have to be perfect ,or will paint cover tiny defects?I know with chrome plating,the surface has to be perfect.Thanks.Charlie
PS The reason I would settle for a less than perfect surface is that hand steel-wool-600 grit sandpaper is very hard work!I don't want to do more than is necessary to get a good result(or take off more metal than is necessary)
