Otherwise, I have used a number of regular automotive 2k clear coats, and the two I find to be the best are Metalux VOC 4.2, and DNA Diamond Clear. Both of these are high solids, which I believe makes a far superior coating. They have outstanding gloss, flow out wonderfully, and both have excellent overspray blend and self-levelling properties, which translate into a much better finish off the gun and requires far less finishing work.

For this I use lacquer/activator/thinner 2:1:1. After this I use an ultra high solids lacquer. You need to be brave with this and get on with it as it goes on in just one coat. Get it wrong and you have to flat it. Once it's coated you'll need to leave it a while for the inevitable 'sink' into the pin holes. Then just flat with 1200 and polish up. If this isn't the problem and it was just a 'whats best' Q then I use automotive 2k's as mentioned above.

Group: Forum Members Posts: 14, Visits: 167	thanks guys for the comments and ill be sure to look up the products mentioned above. whats the devilbiss starting line gun like as i was looking for a new personal paint gun but was looking more at the SRI pro just because thats what ive used before and know they work well. i have also not used the Kapci coating clear before but have used their high build/filler primer which is good and not expensive FLD (18/05/2016) If you're finding that you get little spots where the pin holes are then you need to brush coat a few layers on first to fill out the pin holes.

Can probably get it if I searched for it, but everything here is either 1k acrylic or enamel, or 2k polyurethane (generally an acrylic based polyurethane, polyester polyurethane certainly isn't common). I prefer polyester 2k's myself, but they are special order and have an extremely short shelf life. Polyurethanes cover everything from primers to top coats to clear coats. These are definitely the most commonly used coating for composites work, and would wager they are substantially tougher than acrylic enamels.
