TotalBoat Polyester Structural Repair Putty

After I reinforced a hole in the hull with fiberglass and resin, there was still a low spot. I figured it would take forever to keep filling it in with resin, plus the resin is extremely runny so it is hard to get it to stay in the low spot. I came across this putty and out of the can it is extremely workable, not runny, does not sag and stay put. Even mixing in the liquid hardener does not effect it or make it runny. I applied it to the hull and it literally took one coat and evened the low spot out. I mean it goes on so smooth, and you have plenty of time to work with it before it starts to get tacky. The price is very fair compared to other stuff like Bondo which they say you don't want to use for these types of repairs. I have yet to sand it, but it is extremely hard and nothing an orbital sander can't handle. Hope this review helps as I was going back and forth on what fiberglass to use.

I was fixing some holes in the boat and I’ve never actually used the polyester before. I usually use epoxy and personally in the future, I just will use epoxy and fiberglass. Nonetheless this does solidify well. This does appear very solid. I think it’s a good quality polyester, but I wouldn’t use it personally again.

Worked great for making a piece that was missing on the rear wheel well on a 1966 corvette

I would buy again. Easy to use. No issue, just make sure you are in a well-ventilated area.

This works great for what I need. A bit difficult in sanding it down a bit but works well in filling the gaps

Great product!! A+

First time using this type of filler. Cure time was predictable. Mixed easily on my board. Spread smoothly. Where I did have some unevenness I was able to fill after initial curing Minimal sanding, great finish. Been over a year out in the weather. No pitting, cracking or shrinkage

I love this putty. I use to fix dings, splits and cracks in the hull. It’s great for filling screw holes that were stripped and no longer able to mount hardware with screws. It doesn’t drip which makes it much easier to work with. The volatile organic compound odor is very intense. Definitely either wear a VOC filter mask or work in an area with a lot of ventilation. It is hard to sand precisely so try to avoid using excess material. If you need precise sanding, you’ll need a fairing coat.

Worked as expected.

Great product. Works as directed.
