After primer is applied, use 220-grit sandpaper for a smooth surface. Change sandpaper frequently, and wipe the primer down to remove dust. Vacuum the floor to remove the dust, and keep it from flying back up onto the primered surface.
After priming a gas tank you should use an 800 grit sandpaper before you spray on the base coat. Be sure the let the primer dry thoroughly before you sand.
400 grit sandpaper, before sanding melamine wash the surface with TSP soap and the rinse with water to remove any TSP residue
Some rotary pumps are self-priming when dry. These pumps have a priming chamber that automatically does the self-priming when the pump is not in use. To prime a pump yourself, the priming plug should be removed. Water should then be poured into the pump. The entire priming process should take no longer than five minutes. If it takes longer than that, it could be indicative of a mechanical problem.
no
No the e-coat is a electro-static primer. It is very durable just make sure it is scuffed properly before priming or painting.
about 2 hours
For pure sanding of bondo or metal, No. If you are preping to paint or sanding primer you should use Wet or Dry sandpaper and sand wet.
Initially, you can use as any grit you need to get the area straight, once it gets near that stage you need to step up in the grit to remove scratch marks. I would not prime any surface with greater sanding marks than were done with 220 grit. After priming I would block with 400 grit wet or dry
No. The terms "rimfire" & "centerfire" should self-explain. On rimfire the priming compound is in the rim of the cartridge and on centerfire the primer with the priming compound is in the center of the cartridge.
one-half
220 3m its a finer sand paper you can take the paint as low as you want with it it works great. You should always prime over a 220 grit scratch. It is the perfect size grit. If you are sanding primer so you can apply topcoat, finish with 400grit dry on a machine (DA) or 500 wet sand for a solid color enamel. Basecoat products, particularly metallics and pearls, need to be applied over a substrate that has been wet sanded with 600 grit.
Using Sandpaper on HeadlightsNo you should never use sandpaper on your headlights. Using sandpaper to clean headlights is an archaic, low tech approach to a modern problem.Only someone who does not understand the difference between plastic objects and a plastic refractive lens would consider using something as aggressive as sandpaper on plastic headlights.Sandpaper strips away the surface of the lens along with the factory protective UV coating. You actually have to resurface your headlight when you use sandpaper. And no aftermarket kit or sealer can replace the UV layer to oem specs.Polish is a better solution than Sandpaper but it too can also remove part of the lens surface. A pure liquid Deoxidizer is the best solution for removing oxidation without damaging the lens surface.
The sentence should be punctuated as: "Not yet, Dave shouted. Andy, you still need to buy some sandpaper."
