What 2nd has beat the G250?

[LEO1982]

Thanks. The current G260 has a carbon fiber shell. The carbon fiber G250 are hydro dip and then finished with 2K (SprayMax) urethane clear. The finish is tough and resistant to solvents but anything can be scratched if one works at it hard enough.

I was dipping some motorcycle parts and did a couple of my G250 fleet to see how it would turn out. I like them. I also found on Thinguniverse G250 bump covers and had an online printer make me four from the file.

I used a red metallic and blue metallic base coat (OHW products) intended to adhere dip films. It is what I had bought for the motorcycle project .

Great, time to give the G250 a new look! Does it need to be sanded before spraying the primer?

I degreased only. It would not hurt to use a 600 or 1000 grit paper to very lightly scuff and then degrease a second time. The OHW product I used does not require adhesion promoters etc. You will need to follow the recommendations of the materials you use. IMO, and my experience, the polyamide material that the G250 case is made from does not require flaming prior to coating.

Truthfully, I have had good success on gun stocks using Krylon as a base. But Krylon and similar do not remain reactive with the hydrodip film but for about a day whereas some hydrodip specific products remain open for several weeks.

There are new 1K topcoats available but I have never used anything but a 2K clear. The problem with 2K is it is a bottle in a bottle and once mixed it has a pot life of maybe a few days. The 2K chemicals also produce isocyanate gas so you really need to use forced air source (scuba?) for breathing or, hmmm, for a small project, wearing appropriate eye protection, I practice my free dive breath holding skills, . You, know, I am the author of "safety is way over rated" so -----. One exposure is not going to hurt or kill you but we do want to limit our life exposure to such things for our long term health, you know, so we can keep scuba diving.

Selfie, night dive in Red Sea, G250s on a Mark 2 Evo:



Edit to add, just for general information, why do I take these weird selfies, I always take an initial shot with my camera, a selfie, on descent, to set my camera and strobe settings to ball park for the dive conditions. Or sometimes I will just roll over and take a shot something like this for settings check:
