Have you ever wondered what happens when you spray paint something without thoroughly cleaning the metal first? You get to paint it again. When I painted the seat frames of my BD-4C airplane back on the 14th, I was hurrying to finish up in time for an evening commitment. Big mistake. Most of the paint adhered nicely but I have several spots that look like this.
Ugh. I’ll be cleaning off the paint and cleaning up the metal, like I should have done the first time around. Then I get to paint it again.
That’ll teach me about hurrying through a job….
What’s the old saying? The hurrier I go the behinder I get!
We all make those kind of mistakes. Just keep trucking!
As an olde paint & adhesives chemist, the mortal sin of lifting is a dirty substrate to which very few primers & adhesives & tapes will adhere. Sin once, but sin no more…..unless you’re sinful.
Thanks for the “encouragement,” guys. So how come the crud adheres better than the primer? Maybe the paint companies could make a crud-based paint that would stick to anything. :-/
