Paint remover

[alldodge]

My neighbor (25 years in the Paint and Body Business) Says they use this on Corvettes. Works great and WON'T harm the fiberglass.

Sounds good, but this is a paint stripper, correct?

 

[Woodonglass]

Yup, He says it's really good stuff and works great. they call it a Paint Remover.

 

[alldodge]

Well the latest and the great.... at least at this current point in time

Reading about VC Performance and talking to Interlux it was determined I could not go with blasting. Interlux says it needs to be sanded with 80 grit and no paint can remain prior to painting. So I ordered a 2 gallon kit of VC and 2 gallons of fiberglass solvent wash 202 from iboats. Took the cruiser over to a marine dealer to sand it at $60 a foot.

Stuff came in from iboats but was missing one gallon of activator. Called iboats and they sent the missing gallon but received no email or call about if it was shipped. Called 5 days later and was told they would check into it. Later in the afternoon UPS shows up with my missing gallon.

No need to read, just venting
Dealer said I will have the boat Friday and he will call, no call Friday so I call 2 hours before closing. Things happened and will be able to finish up in a couple hours Monday, he will call. Monday no call, so I wait till today (Tuesday) and call. Dealer says it should be done after lunch. I say OK I'll be there at 1PM will that work. Sure no problem.

Get there at 1:30 and see the boat as I'm driving up ready to be hooked up, but wait, not all the paint is off. Go inside and discuss, fella I have been working with says, I must have misunderstood. Bunch other ramblings about don't up want primer, I say no it cannot have any paint what so ever. Head guy walks up and listens and says I'm correct to apply VC everything must be removed. So he says it will be done by the end of the week. I'm not holding my breath.

Maybe read
They did do a nice sand job trying to only remove the bottom paint and not mess much with the barrier coat, I give them kudos for that. Just ordered another 2 gallon kit of VC from iboats, figuring, more coats might be better, and hope they don't go wild since they have to do it again

At the end of the story, folks just don't call or inform out of normal operations. iboats or dealer, guess everyone fingures if there is a problem, we will call :facepalm:

 

[alldodge]

Anyone know if a dump gun can be used to spray epoxy?

 

[Woodonglass]

You can spray epoxy but...IMHO it's not advisable. Dump gun with a 4-5mm tip would prolly work. :noidea:

Talked to Glass Dave on OSO and said to use a pressure the HF pressure pot with a 1.4 to 1.5 mm sprayer. Picked up one which holds 64 oz from HF, some MEK from another place, and another 2 gallons of VC from iboats.

Got the boat back today and Lake Cumberland Marine did a great job. They found after removing all the barrier coat that some areas of the Gel was thin and started to flake. So they continued to sand to make sure it was all smooth. While I still have issues with communication, they do great work, and very happy with the results.

Have all my stuff and will be painting soon and will post how it turns out.

Boat yards in general are not known for their communication skills

Anyway . . . I did not realize that the gelcoat was going to be removed throughout this process. Are you going to add back a layer of gelcoat, or just go with the VC?

 

[alldodge]

The VC has to have either Gel or fiberglass to adhere, no pint can be present. So I'm just going to wash with 202 and then paint. Have 4 gallons so should get 4 coats on easy. Just need to time it so I can get the coats on before it blushes

You are a braver man than I, Gunga Din!
I have an ablative bottom paint as the PO kept it in a slip. However, I now keep it on a trailer and that blue rubs off on everything, especially me!
I'm very interested in seeing the finished product and learning how you get there from here.
Good luck!

Been reading how to use the sprayer, and its simple enough but going to need to go get some very small cleaning brushes. Says to clean the sprayer if not used after 5 minutes. Dang 5 minutes, kind of thinking I could stretch that a tad with using epoxy (doesn't dry as fast). In any case need to make sure I have some help mixing the paint. This way I can start spraying while another batch is being mixed.

The VC does list it having a 5 hour pot life at 73 degrees

Did some closer inspection now that its been lifted off the trailer. Going to do a bit more sanding in some spots. It looks good, but appears the guy on the starboard side did a better job then the guy on the port. Still see some paint on the lip just below water line. Understand why they didn't get it all off, but need to figure out what to use my self. Maybe a sanding cone or some such thing

 

[alldodge]

Think I'm going to try a wire wheel on a drill to get the paint off. May also pick up some sanding cones. The boat is off the trailer, so tomorrow I plan to move my compressor over. Make a trip to Bowling Green to pick up other stuff to be ready when I can have two good days to put 4 coats on.

Seeing your boat suspended like that is scary to me

Are you going to use a couple of keel blocks or other support as a safety factor?

Never seen boat jacks like that . . . what type are they?

Those are Yardarms and can handle up to 40K, in the current setup can handle 12K (8K stern, 4K bow). My thought is they are plenty strong and the current settings probably has a design
http://www.yardarm.com/marine_products/boat_handling_jacks.htm

Each jack weights around 200 pounds. The plate on the bottom is 1/2 and the arms that extend are about 1.25 thick. They lock in every 2 inches of lift. Before the trailer was pulled out from under, I shook the boat kind of hard, and it move a bit side to side, but no fore/aft. If the boat was a tad wider I could have used higher settings, but as-is there was about 1/2 inch between fenders and jack.

Had the boat sitting on them for two days before pulling trailer. I'm thinking about a extra jack on the keel close to the bow, but still feel pretty good about the setup

 

[alldodge]

Everything is masked off except the boat jacks. Will do those just prior to painting, and still need to laydown some plastic. Think I'll pull the Rinker out before spraying also

 

[alldodge]

Well, might have to go to roller and brush, folks in the know is saying I need to get everything out of the building, and cover up the top half of the boat also. Just saying the spray can and does go everywhere.

 

[alldodge]

Bought rolls of 4mil plastic, and wondering if I can make a tent from the top of my paper. Have a full face mask but wonder if that will be enough. Thinking it might be because epoxy isn't hazardous. Not sure wondering others thoughts?

 

[tpenfield]

spray painting is a PITA unless you have got a spray booth and the proper ventilation. The roller & brush might be the way to go rather than getting the over-spray on everything in the garage/building

 

[tpenfield]

I spray painted my 1981 Honda Prelude (metallic red) and my 1989 T-Bird SC (metallic blue) . . . had to turn my garage into a spray booth on both occasions.

Wondering if you could do the same in your building with some floor-ceiling plastic. :noidea:

 

[alldodge]

I'm leaning that way, just thinking that it would make a smoother finish if I spray. Even if I just spray the bottom and roll the sides. By taping plastic on the sides I'm making a booth, sort of. Figure it should only take maybe 25 minutes to spray the bottom, and could probably get the sides as well. Need to talk to the guy who will help out and see if he has any ideas. Hoping glassdave post to get his thoughts

 

[alldodge]

Rolled plastic under the boat, then used fiberglass wash 202 and cleaned it up. Arms sore, Admiral came in as I was having a beer and asked why not put the first coat on? Said OK, you going to help? She says yep

So mixed up 2 quarts of paint, and let it sit for 30 minutes. Tell ya this stuff is almost thin as water. Figure that's why there should be at least 3 coats. Kind of thought it would take more then 2 quarts to paint the hull, but no we had next to nothing left, but did have a tad bit.

So here is the first coat, tomorrow we get the second coat. And we are rolling it on with brush touch up
