Sanity, gotta admire anyone with that muck "SPUNK".
I talk to Dr. Pete almost everyday, he helps me thru the "hills and valleys".
May have a new twist on the DR. thing, we could have a 1-800-275-7383= 1-800-ASK-PETE.
He could do it like one of those 1-900 numbers and charge 7.00 a minute.
There have to be ways to supplement our income in these trying economic times, this could be your "calling" Pete........Boat dr

Yes, The 1oz. is a minimum otherwise you end up with a translucent gel.

I'd tint the whole 1 gal. batch so you don't have to worry about small quantity color matching.

Thanks Pete. My biggest worry is getting the gel to match. The application will be pleasurable work. I can mix the tint in the gel beforehand and store till ready to apply. I'll try mixing a pint and see how it goes. It surprised me to find out that you "must" use 1 oz. of tint per gallon, yet you can add as much as you need of any or all colors to reach your desired shade. It's a poly paste and it won't alter the gelcoat as far as using the reducer or MEKP. That doesn't make sense if you "must" use one oz.
I picked up some measuring spoons at the dollar store for this.

Good Morning Pete,

I purchased the reducer that the manufacturer recommended and supplied. You are correct.
A few manufacturers recommend not using a reducer with their gel coat. Blink bought a gel gun that came with #6 and I purchased additional tips #3, #4 & #5. I can't recall the mm sizes off hand, but again I purchased what was recommended. #4 was the recommended size, so I bought 1 size up and 1 down. The specs are 5% on the reducer, but depending on the weather, they said (as well as the specs) that you can add more or less. Longer dry to "tacky" time if you add more. The MEKP works the same way.
If the gel gun isn't working for me, we have the auto paint gun too.

Michelle,
I don't recall ever discussing reducers (solvents) unless it was way back when I mentioned always going with what the manufacturer of the gell recommends. I know I mentioned fluid tip size recommendations and it's relationship to viscosity. Did you get the solvent too? Did you get reduction specs?

Hey Lee, need some muscle here! Can't get the dang gel coat gallons opened! Lids must be gelled on. Co-worker stopped by and he couldn't open them either. Guess I'll bring the channnel locks home to loosen. Just wanted to see what it looked like.

Time to move this back to the front so I am able to keep all of my gel together.
I have everything to begin - Good News! It is raining today and is forecasted to rain throughout Sunday. Not so good news, but I'll be doubly ready when the rain goes away. I even called the gel supplier and asked about applying gel on a rainy day in hopes that he would say Do It! Didn't happen. I will continue in steps though, as the garage walls need covered, as well as the floor. And I'll wipe the mustang down with acetone again. No sweat!

Steve, Congratulations to you and your family!
Yes, we are going to try mixing the gel ourselves. I'm ordering 5 gal. so that should give us a fair amount to play with till we get the right mix.

Eric, No, not sealing with anything first. It's been recommended that the gel goes right over the existing gel.

Gary, Thank you. I appreciate your offer. But I need 4 oz. of tint per gallon.
Your trailer looks great and to think they were able to blast while you waited makes it all the nicer.
I like what you did with your seats. I don't have a glove box. I like the idea of being able to turn the seat around. I'm thinking of a light gray carpet, white seats with black beading in mine. I like where your battery box is too. I would really like to have a "horse". Blink saw a transport company truck that had a stallion logo on it. It looked similar to the "Mustang". I put the company in my favorites and we are tossing around "how" to have one made.

Michelle, I have minicrafts color samples http://www.minicraft.com/fantex.htm
If you want I could send those samples that are close to your yucky tan. You might find a stock color thats close enough.As to trailers and sandblasting,I got this done for 200,done same day I called and while I waited.In my area the prices were all pretty close.

I have no front seats at all. I have the rear seat. I pulled the thread on how to make the seats. I wanted the passenger seat to face backwards.

I thought you needed a fresh air mask to shoot this kind of stuff.


The fresh air supplied masks are recommended for the 2 part poly paints but not absolutely needed. The gel and the poly both have the solvents but a mask with the proper solvent type cartridges will do it. It's the isocyanate catalyst in the linear polys that is the nasty stuff! A P100 rated cartridge will take care of it if you're in a room with some ventilation and not down in a bilge!

Greg,
Bill started with a cheap "disposable" spatter type gun that he got from US Composites. He then switched to a I believe a siphon feed and had to really reduce the gel to get it through the gun.
I've had good luck with a pressure feed with a generous size fluid tip. You get quite a lot of orange peel but you will get it no matter how you shoot it. Gel doesn't like to be atomized!!

Sean, you should join in and become a Steeler fan. Or you should go to Seven Springs or Hidden Valley...that way you would have the slopes to yourself. We are supposed to get quite a bit of snow Tues into Wed.

Pete, those coveralls are very becoming. I think the ones I got have the hood and boot covers. Although, the bouffant kind of catches my eye.

Pete, did the passenger seat always face forward on the 66 mustangs?
