Title: Using Low and Mid -Solids 2K Clear
Post by: Frank Imbriaco on July 03, 2017, 06:33:44 PM

Most know that the solids in 2K clear = more weight. So, does  it stand to reason that High Solids should be something to avoid ?
I'm using 2K  clear on an  electric powered ship. Have used Dupont Chromaseal( a high solids)  in the past with nice results . Except, its heavy stuff.
If you have shot with a 2K low or mid-solids clear, please report your experiences.
Thanks

Frank,
If you are finishing an electric why not just use clear Brodak dope? It would be the lightest. The only reason to use the 2K or auto 2 parts is to get better fuel proofing. Dope that is fully gassed off is a very hard surface and gives the best gloss.

Because I use basecoat/ clearcoat finishes.

Frank,
From what know of the base coat/ clear coat the clear is a tough material that should buff out great. Is the 2K that you are speaking of the clear coat for the particular paint brand you are using or Diamond 2K? If the former since there is no fuel to worry about I think you could use the lightest one and be fine. Maybe do a test on a small part or scrape to see the difference between the coverage and gloss.
