I decided I did not want the turn signal indicators in the hood scoop so...
|I roughed up the edges of the fiberglass with 180|
|Then laid down fiberglass cloth with fiberglass resin, using a simple Bondo fiberglass patch kit that can be had anywhere (even Wal*Mart) for $20. It's cheaper than buying the components on their own and having a lot of material left over in the end.|
|This is with the cured cloth/resin.|
|I then skimmed the opening with Evercoat fiberglass filler.|
|And skimmed that with Evercoat EZ Sand 2k glazing putty for a smooth finish.|
|The next step was to spray with Epoxy, then Slick Sand. I bought this gun from TCP Global for about $45...with a 2.5 mm tip it's nothing short of a cannon. It is fantastic quality and shoots the Slick Sand unreduced perfectly.|
|After the fiberglass had UV cured by sitting outside for 5 days, I shot it with Epoxy.|
|And there is no trace of a hole ever being present in the turn signal openings. Any tiny imperfections will get covered up by the Slick Sand.|
- Buy a cheap gun to shoot Slick Sand. That way if it sets up in your gun, you're not out your good gun.
- Buy a gun with a large enough tip. It seems somewhat defeating the point if you buy a high build product, only to be thinned out so it doesn't build as well. I think Ever Coat recommends at least a 2.0 mm tip. My 2.5 mm tip was plenty sufficient.
- Do not leave the Slick Sand in your gun for more than 30 minutes or it risks setting up. I did not mix more than I could shoot in 30 minutes. At the moment I added the hardener, I started the timer, which would include mixing, spraying, and flash times.
- Do not use an in-gun strainer, or even filter the product as it pours into the gun. The gun I bought had an internal strainer and the Slick Sand basically spit and sprayed poorly. I removed that and was back in business. I eventually even stopped filtering it as I poured it into the gun because it would take so long to drain through my filter. Even unfiltered I had no hitches when spraying.
- Start cutting with 120, then move to 180 or 220 for final blocking. Once the initial layer is off, it sands very nicely. It will spray on with lots of peel so the initial blocking seems to bounce right over the top.
- A lot does not go a very long way. I mix up half a quart at a time. I pour out 16 ounces, and then add half a tube of hardener (11 ml, to be exact) to the 16 ounces. The tube of hardener has graduations on the side so you can see how much to add. One gallon comes with four tubes of hardener; one tube per quart. Mix well (it greatly thickens upon adding the hardener) then spray, allowing for adequate flash. Half a quart basically allowed me to shoot one coat on my hood scoop, door, roof, and trunk lid before it was all gone. I then poured some lacquer thinner in the cup, swished around, and sprayed the lacquer thinner out to get everything out of the gun's system, then mixed up more and sprayed a second round. In doing this I never end up wasting any and I don't risk it setting around too long and setting up in my gun.
- Spray when it's cool outside to keep it from setting up too fast. I sprayed early on when it was 60's and 70's out. It's been over 100 consistently for the last week or two (108F yesterday) and I'm glad I got most of it out of the way.
- Mask off anything you don't want overspray on WELL. This is definitely overspray you don't want to have to remove. Additionally, it makes the floor sticky so I laid a blue tarp on the floor and painted over this. I had read about this ahead of time so did not have to end up with a sticky garage floor.
Final thoughs on Slick Sand: Amazing build and sands great once you've cut off the top layer. You can keep blocking and blocking and blocking before you see signs of breaking through. The advantage of this is you can keep blocking until the last of that guide coat is gone and still have room to shoot another layer of guide coat and block it again. It did amazing things with my quarter that definitely had a few spots my hand could feel after my metal working (and filler work), which was probably sub par at best, I admit. I was counting on the Slick Sand to be my crutch and it really was.
