    Removing paint from aluminum valve covers and intake manifolds

    Just starting on my new project a 1963 # matching roadster. Some time in the past the owner sprayed a heavy coat of silver paint on both parts. Any advice on how to remove with out damaging the surface ie. paint remover, sand/glass beading or ?. Acetone doesn't do anything.
    Thanks,
    Jeff

      I used Capt Lee's Spray and Strip. It is sold as safe for fiberglass and I used it to strip my 1960. It is also one of the best strippers I have found for stripping paint from just about anything.

          As mentioned above, a chemical stripper will work best.

          Once the paint is off you can assess for condition. Hopefully the previous owner did not bead blast or use an abrasive to scuff the surface prior to the paint being applied. The abrasives and beadblasting may impact returning your parts to original condition.

          If your parts are in good condition uder the paint, you can send the parts out to be re-skinned and they will come back to you ready for judging.

          I have attached a picture of my intake after the re-skining.


          Good Luck!

              Jeff - I've had good results with aerosol/rattle can gasket remover such as NAPA 765-1230. It's gentler than regular strippers but does a great job removing paint and overspray on rocker arm covers, fan blades, etc.

                  Curious, has anyone ever brought parts to a facility that dips parts in acid to remove paint ect ?

                      I have my Intake/ Exhaust manifolds and Valve-covers sandblasted and they look like new and afterwards put the Covers in food oil for some days and they look like new and they are 2 years old after resto now.
