Richardtr3a Posted September 22, 2016 Report Share Posted September 22, 2016 I am planning to sand off my boot lid over the weekend and need some advice. I have a sanding flap fitting for my electric drill which does not seem to even scratch the paint. So I am considering a sanding disc. If I go right back to bare metal will the discs damage the surface and what grade of paper would be best. The inside has some strengthening supports. The top and bottom edge could be treated by my local sandblaster but I am worried that they may distort.. Please advise. Richard & H. Quote Link to post Share on other sites

stuart Posted September 22, 2016 Report Share Posted September 22, 2016 Richard I would be careful using sanding discs, these work very well and dont hurt the surface. http://www.frost.co.uk/100mm-drill-strip-disc.html Stuart. Quote Link to post Share on other sites
nigethomas Posted September 22, 2016 Report Share Posted September 22, 2016 (edited) Morning Richard, When i did all the paintwork on my 4a i took every panel back to metal.I did use nitromors to start with which just took single layer off.That stuff is no where near as good as it was years ago. In the end i used my grinder with a soft 40 grit disc on and sanded all paint off.It took a while but was effective.I then went over with DA sander with 180 grit it seemed the best way to me.make sure ya wear good dust mask though.

Ian Vincent Posted September 22, 2016 Report Share Posted September 22, 2016 Hi Richard, I used Nitromors (old style) to remove most of my paint but then I used the discs that Stuart is recommending for cleaning back to bare metal - they work a treat and leave a nice surface to paint. A word of warning about the discs though, they last pretty well unless you take them across a sharp edge or a sticking up rivet at which point they abrade (the disc) in seconds and you have to use a new one. I used mine in an angle grinder which spins a bit faster than an electric drill and is easier to handle in my view. Machine Mart do cheap angle grinders which work pretty well.

Steve T Posted September 22, 2016 Report Share Posted September 22, 2016 Having tried Nitromors on my 6, I ended up buying some Starchem off of eBay. Fantastic stuff!! It works.....whereas Nitromors doesn't. Quote Link to post Share on other sites

stillp Posted September 22, 2016 Report Share Posted September 22, 2016 Nitromors wouldn't touch the high-build primer that was on my boot lid. However an old rag soaked in old brake fluid, left on for a few days, stripped paint, primer and filler back to bare metal. I used silicone brake fluid when I rebuilt the hydraulics...

McMuttley Posted September 22, 2016 Report Share Posted September 22, 2016 i allow moisture to get between metal and paint, works a treat and is pretty good on all paint types Quote Link to post Share on other sites

david c Posted September 22, 2016 Report Share Posted September 22, 2016 I stripped the whole car, inside and out using strip disks, about twenty in all. Messy / dusty but very efficient and no worrying residue. One small point having stripped off the paint with these disks you do need to re key the surface or the primer will fail, please don't ask me how I know David Quote Link to post Share on other sites
Richardtr3a Posted September 23, 2016 Author Report Share Posted September 23, 2016 Thanks very much for the advice, I will take my discs back to screwfix and buy the recommended ones from Frosts How do you rekey the surface? Thanks Quote Link to post Share on other sites
stuart Posted September 23, 2016 Report Share Posted September 23, 2016 Thanks very much for the advice, I will take my discs back to screwfix and buy the recommended ones from Frosts How do you rekey the surface? Thanks Rub down with 180 grit all over, this will give you a good key and scratches wont be too deep. Stuart. Quote Link to post Share on other sites
had17462 Posted September 23, 2016 Report Share Posted September 23, 2016 Took me 3 hrs this morning starchem stripper then wire wheel on girder for around the edges then finish off with wet and dry then cover with rust buster . Nick Quote Link to post Share on other sites
MikeF Posted September 23, 2016 Report Share Posted September 23, 2016 When using any chemical stripper you must take care to remove ALL traces of it before repainting using something like meths. Small traces will make themselves known by blistering disappointingly soon and of course in hard to treat areas. Mike Quote Link to post Share on other sites
