I use a sheet of that foam insulation board with the foil backing on it--its fairly cheap at home depot or similar stores,the pink stuff without the foil works good too,but it isnt as rugged as the foil faced stuff.This keeps you off the cold floor,and wont soak up fluids like a sponge like the egg crate matress pads do--I've used the egg crate foam and carpet underlayment foam for soaking up spills in the shop--once I lost 3 qts of dextron from my van during a motor swap-I stupidly stuffed a rag in the dipstick hole,and at acted like a wick--drained three quuarts all over the floor overnight-,had to swim in it until I thought of using the egg crate stuff to soak it up--then I put it in the woodstove--had plenty of heat for the next half hour--but the smell and smoke was horrible--more than one neighbor was giving me dirty looks that day! /forums/images/graemlins/blush.gif /forums/images/graemlins/tongue.gif
