The GoJo worked pretty well for me. As far the the brushes I keep trashing them too. Just kep getting the cheapest ones I could find! But in your case I wouldn't want to risk bristles getting stuck in the resin because of a cheap brush.
CF Resin/Layering Questions
I've just started working with CF and I have a question some of you may be able to help with. For my 1st piece I am overlaying an armrest. I have already done the following:
1) attached fabric to armrest
2) coated with resin and allowed to dry until tacky (45mins-1hr)
3) laid a 2nd coat of resin
4) allowed the 2nd coat to dry completely (rock hard).
Now I see that there are a couple of low spots that could really go for another coat. I think they are too deep to just use a spray on clearcoat. When it comes to laying down additional layers of resin, now that the top coat is hard, do I have to sand and clean the hard resin top coat before applying more resin? I'm hoping I can just spread more on it without sanding but I figured I would ask before I take a chance of ruining my current work.
FWIW, I am using a special polyurethane resin that dries perfectly clear. This is not the same as your standard fiberglassing resin which tends to dry an amber color. Not sure if that would make a difference.
Also, if the resin becomes chipped/cracked is it ok to apply resin on top of that or do you have to sand/clean first? I ask "just in case". I do not have any cracking as of yet.
I'm also curious as to what you all use to remove resin from your skin and brushes. So far I have just been trashing the brushes after each single use
And I found that soap and water don't do JACK for cleaning resin off your skin! I ound my hands were covered with paper towel scraps after washing up :lol: I thought someon said "Gojo" works well :dunno: I have been using a pair of Gojo gloves and they rock but I don't always wear them while working with the resin.
Thoughts? Tips? TIA!

Wear surgical gloves, that's what I would wear when working with any type of resin. Just pop them off and trash when finished.
As far as brushes, I used foam brushes and dispose after each use.

Update: I "globbed" on another layer of resin without sanding the hardened layer 1st. It stuck just fine and appeared perfectly clear. Tonight I will start sanding/smoothing and try to get some pics.
How exactly do you go about polishing it? I have an 8" buffer/polisher but I have no clue what kind of wheel or compound would be used to polish a resin :dunno: Plastic compound I would guess? :dunno:

Treat it as if it was clearcoat. Wetsand, going up to higher grits, and even as high as 3000 if you want the BEST finish and use a medium cut compound, polish, etc.Update: I "globbed"

So I ran into a problem when wetsanding... I used an air DA sander with 3" disc and soft pad and 600grit paper. I cleaned the top of the armres with rubbing alcohol and wipe it with a cloth. Let it dry a few minutes. Then I used a spray bottle to wet the polyester resin coat and hit it with the sander on the lowest setting. The resin started to get cloudy as expected but then thing got very sticky and a greyish "glue" appeared on the surface. It seems to harden after I stop sanding and then is near impossible to remove.

Any idea what I may have done wrong? I see a website talks about selling a "sanding-aid" for the resin I am using but it is not listed in their catalog Think I may need that? I tried hand sanding with 1000grit after the "glue" showed up and as soon as the paper hits that glue it stops. I'm not sure how to remove this sticky stuff without hurting the hardened resin underneath :dunno: Thoughts?
