Best of luck, I tried to do it on a galant vr4 engine cover, after the third attempt I took it to the kit supplier to do who took three attempts alright in the end, but that was 6 years ago , kits are a lot better now, prep is very important, primer and top coat very important must be clean and flawless, also water temp, I think the house bath maybe to small for engine cover, but hey good luck looking forward to see the results.
