automotive clear coat

Post by jl1958 » Sun Apr 06, 2008 1:06 pm

I would like to know of any one has used automotive clear on there wood? And if so has it held up? I have a body shop and use clear with flex-add in it. I know it will flex on parts and not crack. And it was uv protectant.

It works great! Ive used it for several years and it holds up much better than varnish. The key is to apply multiple coats for a high build surface. You will need to apply 3 times as much clear as you would for an automotive application. Also,you need to seal the wood with a penetrating epoxy before applying the clear. I generally use 2 wet coats of smiths penetrating epoxy and let the stuff cure for a couple of days before applying the clear.Scuff the epoxy with a scotch brite pad before applying the clear.
You can wet sand and buff this surface the same way we do on automotive applications to achieve a flawless, flat, perfect high gloss finish.
The downsides of this system are: 1 You need to be a skilled professional to apply these materials. 2 This is a very expensive way to finish tour boat. 3 Its a lot more work than varnish.

By the way you don't need the flex additive as only stays active for a few days after application. All of the flex properties leave the clear after a few days of curing.

I was searching for the thread that included your posts about using this method about a year ago but couldn't come up with it. I'm still amazed that it doesn't crack, being such a hard surface.

I prefer PPG 2021 however, since it is so expensive, on large areas I use Transtar 6841

Will clear stick to varnish?

Post by chriscraft55 » Mon Dec 21, 2009 10:16 pm

Has anyone ever tried to apply automotive clear coat over varnish? I like the idea of the clear coat but it will not give that golden color like varnish does.

It comes off the boat in big sheets. Dings and scratches are next to impossible to repair.

Stick with marine spar varnish. Leave the auto finish on the car.

Clear Coat over Varnish

Post by Commodore_Don » Wed Dec 23, 2009 1:39 pm

There is a shop on Manchester Rd. South of Akron, OH by the name of BoatCraft which is doing some absolutely gorgeous, show-winning restoration work on classic wooden boats. Joe Hodges uses PPG over varnish almost exclusively. Our own 1951 Chris-Craft 17ft. Special Runabout is just one of many boats which Joe has refinished. John Vorhies's "Sashay", a 1939 23 ft. Triple Cockpit Custom Runabout is another. Plus there are numberous others.

We scuffed a long scratch on the starboard stern quarter while launching at the Chautauqua Show this past summer. Had the clear coat not been over the varnish it would have been a horrible-looking disaster, but I was able to hand buff out the long scratch so that it was not even visible. The gorgeous finish on our boat has gotten three more jobs for BoatCraft.

Since I am not an expert on this and Joe Hodges is, I'd suggest that anyone wanting more info should give him a call at 330-882-9755.

wood boat

The wood boats with spar varnishes seem to age nicely and are easy to spruce up and refresh the finish with very little effort. The automotive finishes may give a deeper finish faster,but donot have the same durability,repairability,amber,flex,and general staying power of the spar varnishes.guess I am old fashion, I even like the old smelly flathead engines, steve
