Talking Tree Photo sent me his tutorial of how to paint you MFT lenses ith Rubberized Truck-bed Undercoating:
The only reservation I had about my mirrorless gear is the fact that some of my lenses felt pretty plasticky including the cheap lens hoods that came with some primes. After thinking long and hard about it, I felt like things should have some extra protection implemented. So I took the liberty of painting my lenses in rubberized undercoating to toughen them up a bit and it really works like a charm!
The best recommendation that I can give is to use Evercoat Automotive Premium Rubberized Undercoating (here on Amazon for $12) for a real heavy duty job. This is by far the toughest paint for protecting expensive lenses if you want to go down this route and give it a try.
All I used was electrical black tape to cover up areas that I didn’t want exposed to rubberized undercoating and it takes about an hour to dry and 24 hours to completely set before the smell starts to fade after the paint job is completed. Sometime I put a second coat on to be extra safe but be careful not to over-do it!
The end result is this; It will also make cheaper plastic lenses feel much more durable and weather resistant. It seems to help my equipment hold up much better under heavier usage and stay new longer.
Thanks Talking Tree Photo for the great tip!
