Anyone ever use a Preval Sprayer

[SJS101]

I want to apply a gelcoat to my fiberglass slide and found some good review of this product. Curious if anyone has used this device to apply a fiberglass gelcoat to refinish a slide.

I've used them for auto touch-up, and they worked well. It's on the order of a rattle can that you can fill yourself. It seems like gel coat is pretty thick for use in that. But, then I've never sprayed on gel coat.

So, should gel coat be brushed on instead?

It's been a long time since I did any Fiberglas work, and it was on a boat, not a pool slide. You better wait for someone else to answer this one.

I have used those over the years. Like Chief, mostly for auto applications. IMO these would be too anemic for gelcoat application. Besides these sprayers have been sporadic performers....sometimes work well and other times nada.

After looking at my slide really closely I may be able to get away with using 3M Fiberglass Restorer and Wax. May not need to redo the gel coat after all. This stuff looks like it does a great job restoring shine to fiberglass boats.

A power buffer would probably help remove oxidation and polish the surface.

Thanks chief...I think that's the route I will take and see if I get the results I want.

Hey guys! I know I'm late to this but in case someone stumbles upon this through a search, gelcoat may be thinned for use in a Portable Preval Sprayer with styrene monomer. The Sprayer is an amazing spray system however acetone is NOT recommended except in clean-up. Do not use more than 15% by volume of thinner, and always add thinner, tint, OPR metal flake first then add the Catalyst or Hardener and mix thoroughly. Over thinning will result in an inadequate thickness for full curing.
