Rating kbs diamond clear coat and #1 thinner
I think it is a very good clear coat I use it on fishing lures crankbaits and it works very well and is very durable so far I also like the easiness of it dip it and hang it I usually do 2 coats but I love it no more mixing 2 part epoxy for me and I think its more durable than 2 part epoxies so thanks for a great product and if you have any new products I will be glad to test them for you again thanks

Rating Thinner Reduction Use
Application: Reduced 10% and HVLP shot at 35psi. 24hr dry. Knocked off any dust nubs with 320grit. 2nd coat laid on a little heavier now that I have a feel for it. After 1st coat your could still see the pits where rust was, after 2nd coat they are gone - Talk about flow out! Used a guide coat and sanded to verify everything is filled, no sign of the pits at all. Then a 3rd double wet coat reduced a bit more for a smooth finish. Really did not need the 3rd coat for filling, could have left it at 2 coats and skipped the guide coat. Heck I was expecting to use 2K primer surfacer to get it all filled and smooth.

Rating A Great Covering Paint
I have been using KBS Coatings for several years now and find them to be superior to other similar products. I especially like the Customer Service and assistance from this company. Being in the painting business for well over 50 years has given me the opportunity to try many products. I like this one especially.

Rating Thinned Diamond Clear for Preval Sprayer
When it come to painting using anything butt a rattle can I was brand new to it. Was my first time praying KBS products and having to thin the paint for use with the Pre-val Sprayer system. You need to use this product as instructed and not how you would normal treat other paints. Of course it is a paint thinner but I'm talking about using KBS paints like rust seal. When thinning for use with the sprayer I found that %25 was just5 about perfect. I am in a warmer climate and it was in the middle of summer so folks else where I would assume may only need about %15. All in all quite happy. Pre-val doesnt make you a star either and I dont think they are just a good as a professional spray gun (even though I've never used one). Didn't seem as if the paint atomized.
