Would SEM self etching primer be suitable to use on interior aluminum wing parts by itself for corrosion protection without any top coating?
Per supplier, I have spoken to many customers about this application and although it seems to work for them, Self Etching Primer is not intended to be used as a topcoat. My recommendation would be to use our EZ Coat product. It is a direct to metal and aluminum topcoat that has excellent adhesion and is available in 6 colors (Black, Olive Green, Light Green, Gray, Tan, Olive Brown). See "Alternate Items" for a link to the web page.
Is this SEM self etching primer dope-proof?
This self etching primer is primarily used on metal or plastic parts, and nitrate/butyrate dopes are used on fabric. We could not find any information on how well it would work with dope.
