I did it with 3 plastic quart cups filled to about 750 ml. The first coat took a little more to fill the deeper pattern of the 1708. so it should be just right if you have 3 full quarts. I would mix in 10% styrene (75cc)in each of the 3 containers (and wax for the last coat) and bring all 3 on a board and keep it in the tank tub. I would add MEKP to only the cup I was using.  On that note I was using about 3-4 CC’s MEKP per 750 cc which is really light but it has been quite warm and the gel coat was kicking off very quickly so mixing small batches will allow you to adjust as needed instead of wasting a big pot if it wanted to kick quick. I used the purple 3 and 4 inch mini rollers from harbor freight. I would rub the rollers with a gloved hand to try to loosen any fibers from the roller but even if some came out onto the gel I would clean them with a 2” Chip brush. I would start at the bow with the 4 inch and then for the 3rd batch I would grab the 3” both because it fit better under the transom bulkhead and I didn’t want gel kicking off on the roller. I poured right out of the container and spread it with the roller bypassing the use of a roller tray as it wasn’t needed and acetone isn’t exactly cheap. I would throw the rollers out as $3.49 for two 3” rollers is about how much acetone cost I was using to clean the rollers to get maybe one more use out of it but you never really get a roller clean. Same with chip brushes… I got the box at harbor freight which came to $0.25 or so a brush so wasn’t worth the acetone.

Thank you Rick..  here are some hatch pictures. Beveled the core this time. This I ne 8s matte x 2 then lhen 1708, core, matte, 1708, plastic, and finally battery

This is my “working layer” of gel coat. Looks great in the pics but it is not perfect. Unfortunately the transition from existing cap to floor is a prominent hump but I have to settle for strength over aesthetics. As beautiful as I want it to look the goal is a fishing boat and not a factory restoration show piece…. Well maybe a little of both lol. I’m fairly happy with it.  This is the result of one sprayed coat, 3 rolled coats and a final rolled coat with wax. 5 coats. The last 3 were thinned 10% with styrene. Straight gel coat would not self level at all. I didn’t have much of a plan except to keep adding coats until I could no longer see the striations of the 1708. I have a good build up now and will leave this coat until all the transom and cap work are done then I will fair it clean and flat in preparation for final 2 coats of sprayed gelcoat with duratec. This way I don’t have to be medicinally clean with all the work still to be done as the top layer will be sanded away. Next is to finish the inner transom wall and all the cosmetics of the cap. I don’t want to have any dirty work left when I return to finishing the floor.

Thank you rick

I used 2AWG for the trolling motor. Batts are in the console. Then I'll use the trolling motor leads from the terminals I installed. I used 2/0 for the starting battery cable.
