Hello folks. In a bit of a bind here. I've been working on my wings outdoors (Aluminum, Aeronca Sedan) Finished stripping them of the old paint. Next step is to acid etch, conversion coat and prime. Running out of warm temps, mostly down in the 50's F here or less. The Poly-fiber primer is advertised to work down to near freezing temps, but I can't find any minimum temps listed for conversion coating. Someone on another group said I shouldn't try it below 70F. Any thoughts? Also, how immediate should conversion coating be applied after the acid etch? I'm wondering about doing the acid etch one day and the conversion coating the next day. Thanks!
