Well the flooring is from "the ultimate garage", the tiles were from the molson indi expo and I was able to make an excellent deal. If I recall correctly the cost was well under $3 a square foot...vs the usual $6 Square foot for race deck. The rest was just a matter of getting together materials from home depot and rona for the bench/carpeting/paint. For the entire remake including banners, ford stuff, etc I was well under $900. There are also dog doors into the garage from both the outside and from the inside of the house into the garage to allow the pupps access to the yard and for security. If you love a nice floor that's easy to stand on for long periods, and tough enough to work on then the race deck flooring is definately the way to go. Epoxy paint was not an option due to the significant damage to my concreate over the yrs. Now if you include the car into the price of the garage renovation...you may run a bit over my $900 statement v.
I don't use a creeper so I can't say..the raised diamond pattern should not create much problem. For putting jacks on the floor I place them on a 1squre foot pc of diamond cut steel place to prevent the feet of the jack from damaging the floors surface, it supports the car and leaves no damage at all.
