[DICK SPADARO]

You will find it easier to use dish washing detergent as a lubricant, you can use it straight out of the bottle or to slow the evaporation, just mix some detergent with a very small amount of water so its a light slime consistency does the job and cleans up easily. You can use the cord method or a thin plastic flexible paddle to spread the seal. 37 coupe gives good advice as to having a helper when doing the job. Silicone sprays or WD 40 run the risk of staining the interior.
