Scott Eastwood: Surf, Strip, Shop Is The New GTL

Scott Eastwood's West Coast take on 'Jersey Shore's gym-tan-laundry involves catching waves, selfies and hitting up a hardware store and yeah ... he's shirtless too.

Eastwood paddled out just north of San Diego, and wouldn't ya know it -- he had to strip down in public to slip in and out of his wetsuit. Check out the pics ... strictly for the surfing, of course, and NOT his ridiculous body.

When it was all said and done, Clint's son hightailed it to Home Depot to do some drilling -- or, sorry ... to buy a drill.
