Reviews

Good quality product. On properly prepped aluminum it sticks like crazy. It wont flake off like the zinc phosphate paints. Applies in multiple thin coats, almost transparent on initial first coat. Shaken well before first use I found that over 24 hrs and re-shaking there was no plugging of the nozzle etc even without inverting the can and clearing the nozzle.

Sprays nice for coverage. Too early to see if it sticks to aluminum.

Great stuff! Has excellent adhesion to stainless steel and aluminum with no surface prep other than cleaning. There is no need to sand or pre-etch. For best durability, should be used with a top coat from the SEM Color Coat line of paints.

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: 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.

Q: 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.
