can this be used on painted surfaces (tables, chairs..) for outdoor protecton and easy cleaning? and is it really clear, so won't change the color?

Yes. I have done this several times. Note that it may change the color slightly (a little yellowish), but it makes the finish much more durable. I recommend a satin or semi-gloss if you want a smooth finish. I've used matte before as well, where I wanted to make the surface a little rougher (distressed furniture, or stairs on a ladder).

Can this bbe thinned to get a smooth finish?

i do not know, i did not try but if you use a hi quality brush its not too bad . I found brush it out 1 time and do not go back over it an the finish is acceptable

I have a table that has a cut out groove all the way around (which i hate). if i use this on top of a gel stain to refinish, will it fill that groove?

My experience with the product was that if it collected heavy in a crack or around a metal fastener, it dried pretty white rather than clear, so I would expect it to not be clear in the groove

Excellent finish on Brichply : easy to use

Used it on birchyply : its amazing crystal clear semi gloss finish looks super premium. Have tried other PU finishes in the past : they are time consuming and also coat is not crystal clear. Easy to apply : will recommend two coats for excellent finish. Brushable application with self leveling feature is amazing - does not leave any brush marks.
