Another of my winter experiments you may find interesting.
Vintagetrailersupply.com sells a nice replacement drip cap. Unfortunately it comes in white and it’s not easy to get off with paint stripper. I tried it once and it took WAY too long. Recently I noticed a video on removing the paint in minutes with a torch. Yes, a torch on thin aluminum. I tried it.
Heat the aluminum very hot until the paint starts to powder.
It only takes a few minutes after which take it to a sink and instantly rub off the powder with a scotch guard sponge.
