There is a device I've heard of that basically planes a run down. Do they work and has anyone used one ? The high solids clear I shot has a couple of runs that I would like to remove before finishing up color sanding.
yes they work, it is basically a short piece of file, glued to a block of wood. if you are careful you can use a razor blade
i've seen them , never used one. i believe they are called nib files , that may help with your search
I take a little block of wood, Maybe 1" X 1" X 2", sand it flat (or radiused if you have to work in a concave area) on a belt sander, contact cement a small piece of 320 (or finer) wet or dry to it and sand away my mistakes quick, cheap and easy. Eastwood sells the files, but I wouldn't spend money on one
I'm a painter by trade. Take a razor blade and bend it a little so theres a slight curve in it. Then using the high spot of the blade carefully scrap the run to shave it down. The bend will keep the corners of the blade from putting a deep scratch in the clear. Just remember to be careful and patient. When you have the run shaved down, wet sand with a small block and some 1000 grit wet/dry paper, then 1500, and finish with 2000-3000. Posted using the Full Custom H.A.M.B. App!

Ppffftttt! It happens to everyone! All the above are right. They work. Be careful because they can woke too well!
I call it a run file. I also use the***** out of it for more than runs. With patience and practice it will flatten those pesky pieces of trash to nothing before sanding. They always leave a sort of "ghost" image of themselves that come back later if you don't. Runs and sags are flow checks aren't they?
I remove runs and other defects on my woodworking projects with a cabinet makers scraper or card scraper. Just a flat piece of sheet metal with a burr turned up on one edge. A broken piece of glass also makes a fine scraper. No reason why they wouldn't work on automotive paints
Yep, used the piece of glass as a scrapper for years doing furniture refinishing. works great, just a little time to learn the correct pressure. Good luck.
You might want to apply a couple of pieces of tape on either side of the run till you can get the feel for it.
Fooled around with sanding tonight. Had a small run on the glove box door. 1000,1200,1500,2000, then a 3000 trizact,no 5000. pad and some machine polish by hand. It worked. The 3m trzact is expensive. O may have created a monster in myself. Was supposed to be a nice driver. I've worked on it for 4 years. Trying to get the dash ready before wiring starts. I'm not looking for a hard shine but a deep glow if that makes any sense. Its been 35 years since Ive painted or polished anything. Everything has changed. Anyone know if there is a substitute for 3M's detailing cloth? At 35.00 each this could get out of hand.
i saw a video where they applied a thin coat of bondo over the run, then sanded the run out. the bondo protected the paint around the run while it was being sanded away. sand until the bondo is gone and finish from there.
Detail cloths are better in the days after IMO. I always rely on used "baby blanket" material from my local wiping cloth supplier. They're even better when they've been washed a time or 2. The old diaper trick still works and so does used terry towels. Never add fabric softener or dryer sheets as their absorbent quality will go south if you do. I always liked Meguires from the 'other side' of the cloth, as in use the liquid that leaks through the opposite side of the cloth followed with a dry cloth. Hard to beat and worth the next day's ache.
