I had a couple of little bits of paint on the edge of my doors that had chipped, so I bought the Renault touch-up and applied 3 coats and then a coat of the touch-up lacquer, having first given the existing metal & paint a light rub with 2000 W&D first and then a good clean. I left this overnight so I assume the paint was fully hardened but when I gave it the lightest of rubs with a soaked bit of 2000 it just wore through the paint. Is this a problem with the paint, me, or the grade of paper?? Thanks
Thanks, I hadn’t thought of that. I had given it a wipe down with white-spirit before applying the paint, it was fully evaporated though, this wouldn’t have caused it could it?? The paint didn’t peal or flake off, as if it hadn’t adhered properly; it just wore away very quickly with just a few very light passes of the paper. I’ve since had a look on t’internet and yes you can get hold of finer paper, but it’s not at for example Halfords. 2000 is usually the finest sold.
I thought white spirit left a residue even after it evaporated? Personally i'd try again with something else as a wipe down. Hot soapy water or petrol would be better than white spirit. And a light touch also helps with the sanding, as Tutur says it wont be fully hardened after a day maybe a month or three depending on how thick it is! The only time ive ever had problems like that is when i've tried to sand it down a couple of hours later (impatient!). Normally the next day is ok with a very light touch, but iv'e always done my touch ups in the summer, im not sure how much longer the cold and the damp would effect the curing/ drying time.
Thanks guys, it will have been left 5 days by the time I look at it next so hopefully will be properly dry then.
Do the touch up multiple times, so dont blob the paint on, build it up. 3000 grit would be a wise move especially on the edge of a door. Look at most detailing shops hey stock the meguiars papers.
Thanks, I had done, I just put 3 or 4 light brushed-on layers. 2000 is all that’s available at Halfords, will try and get to a motor factor at the weekend then and obtain some 3000.
