Re: 1984 Bomber Scout Rebuild
Thanks Jb, I budgeted my self for 2 gals and I think ill just get 2 of both. I REALLY don't wanna run out mid spray. I plan on using PVA and using YD's HF pressure pot method that I found while browsing a thread.
This is how I full spray gel..
1. Get an el-cheapo Harbor Frieght 2 QT pressure pot ( NOT HVLP ).
2. Mix your gelcoat with 25ish % MEK Solvent ( Not the MEKP ) . Its kinda hard to tell how much you would thin because gelcoats are not All the same in viscosity. You want it kinda like tomato soup out of the can before you warm it up.
3. Have your surface all ready to go ( wiped down with acetone .. masked off etc. ).
4. Suit up good. Respo,suit,gloves,goggles with the holes taped up.
5. Have a box of powdered latex gloves, A few gals of acetone, cups , stir sticks, rags, a brush ( for clean up ).
6. Mix up your gel ( approx 10 CC per quart ).
7. put that in your pressure pot and start shooting away. Use side to side spray patterns. Release the trigger at the ends of the swipe. Basically you pull the trigger all the way back when you start your first motion...then release the trigger stopping the fluid ( keep the air still going just not the fluid )..then pull the trigger when coming back on your pass.
8. When you run out of gel.. open the pot up and put a few cups of acetone in there..flush it.
9. mix some more gel and do that over and over untill you have a good couple thick coats on there.
10. Clean your gun well with acetone. When flushing the gun you want to turn off the air leading to your GUN. you should only have a pee stream comeing from the tip of your gun when flushing ( You will need to have a "cheater" valve hooked to the bottom end of the gun itself for adjusting the air pressure to full off at the gun). Its hard to explain .. Ill take some pics of my gun setup so you know what im talking about.
11. wait untill the gel is tacky to the finger but does not pull off..then spray over the gelcoat with PVA (Polyvinyl alcohol).
12.let cure for a day. .. Rinse off with water and start your sanding steps ( Dry or wet-dry is does not matter ).
13.Buff out.
I would suggest that you play with your gun with water to kinda get used to it before you shoot . rinse out with acetone when your done playing around.
Oh..and after your done flushing the gun with acetone..before you spray your PVA .. Flush the gun with WATER !. Then spray your PVA..then flush it again with WATER...then final flush with acetone. PVA and acetone turns to SNOT .
The reason I never release the trigger all the way while spraying ( shutting down the fluid but not the air ) is because if a chunck gets jammed up in the needle while the air is off you will get a solid stream of gelcoat coming out..NOT good lol.
Its really not that hard..but its hard to explain in full detail with all the tricks and stuff..sorry..
Any questions just fire away..
YD.
also, has anybody heard of or used this stuff? Thinking I might do my trailer with it.
