Clear coat cracking...need some help!

I just bought this car and new about it.
The clear coat is beginning to crack in little "x" like spots on the hood and on top of the car..and a little on the trunk.

Now my mechanic said it will totally come off in about 1-3 years (he's a normal mechanic...not a body one! so I cna't take this word for word)

is there anything I can do to maybe buff it with some wax to take this away or am I basically screwed?

or is there something that will lengthen the time it'll take to crack?

any help would be helpful lol

take it to a bodyshop and see if they'll wetsand/buff it for you and see what else they recommend.
if you cant afford to have it resprayed, tell them that, they will still help you out with the information part.

so there's nothing really that I can do myself that you guys know of because money is somewhat an issue!
