Scratches on bottom.
 

We were visiting a new area yesterday and ran aground pretty hard. Lots of scratches in the gel. Not beyond it but you can feel them. They run length wise. Will this hurt the way the boat runs? What is recommended to fill this lines in.
Thanks

depending on how deep they are you may be able to sand and rub them. What i usually do on a clients boat i will put some dykem blue imaging fluid diluted with acetone and wipe it on the scratches. This will make the area easier to see kinda like a tracer coat .Then i will da them out with 400 & 800 grit paper but be careful you don`t burn thru the gel. Gel is only so thick. That is why this is usually a good job for the proffesionals

can you feel the scratches with your fingernail? If not, you may be able to buff..

Yea you can feel it. Had glass guy come out and he is going to redo and fill in the area. He is also going to blueprint the running surface while he is at it.
Thanks for all the help. Wish I could do it myself but it's beyond me.

I have simalar bottom scraches. How much is it costing you if you dont mind.

In fl we have a lot of guys who were employed at Donzi etc and need work. I am paying 600 for redo of bottom fix all gel coat on keel etc. also going to blue print running surface. We are roughing the bottom not talking it to polish. Two day job. It was the back o boat past the step.
