Prepping Your Parts

{mosgoogle}The most important process in painting interior parts is the preparation.  First examine your parts for damage.  If you find any damage on your interior panel pieces, such as gouges, scratches, or any other type of surface imperfections, you will want to sand down any high spots with the 400-grit sandpaper.  Only sand the high spots down and not the entire area that is marred.  For interior trim pieces, do the same, but if you will be sanding down the entire piece for a smooth finish, use the steel wool as well. 

If you want your interior trim pieces to be smooth and have a completely glossy finish, you will need to sand your parts.  Skip this step and move on to cleaning your parts if you will be going with a textured finish.  If not, then use 400-grit sandpaper to sand your pieces smooth.  After you achieve a fairly smooth finish, move on to sanding with the #000 steel wool.  Continue sanding until your parts are as smooth as you would like.

Remember that if you sand your parts, that after cleaning them, you will want to use an adhesion promoter/primer to help the paint stick to your parts and prevent cracking or peeling.

Next, you will need to clean your parts thoroughly.  Start with a good warm soap and water mixture.  A good grease-cutting dish soap such as Dawn is a perfect product for washing parts.  Use a scrub brush and scrub the pieces down.  Rinse the pieces with water, and repeat the process.  If there are still areas that are dirty such as crevices, use a toothbrush to get the dirt out.  Wipe the parts down and let them dry completely.

The last step in cleaning is to use a rag and Isopropyl Alcohol to remove any last traces of dirt and grease.  Let parts dry again.  If you still have dirty or greasy parts, then use a good specialized cleaning product such as Dupli-Color’s Prep Wipe or Grease & Wax Remover.

To fill in any low spots due to imperfections, use LSR Gray Primer/Sealer to fill in minor abrasions and to promote adhesion on hard plastics.  For soft vinyl rips and tears, you will have to search for a vinyl repair kit or replace the part all together.
