Default RE: removing paint from fiberglass fuse

thanks bass, the project turned out so good, I decided to do a 2nd older beat up racer. Heres a few pictures... These types of planes are laid up in a mold with glass, then either balsa or rohacell, and another layer of glass on the inside. I had left some of the Citristrip on over night and I think it somehow got through a couple spots on the wingtip and also the tail. Both areas used Rohacell (similar to foam) as the sandwhich material in the mold. The citristrip seemed to make the rohacell soft and mushy after sitting all night. I cleaned it up as best as I could and over the next couple days those areas stiffened up well. I had to add some glass over those ares as a precaution. Should be completey ready for paint by this weekend, if not sooner.

Guys looks like great stuff this Citri Strip is. I have a question for all users on here. Is this stuff compatible to polyester resin or not. I just found out that my Arrow's fuselage was made with Poly resin and glass cloth!. I just want to make sure before i go and get this stuff if it's worth taking a trip or not for my application.

Well I learned something about Citrastrip last night.. If you are trying to strip something that was painted in a mold you are out of luck with this stuff.. I let it sit over night and still nothing.. I even sanded a spot and put on a ton of it and still nothing.. If I had to guess I would say it's because the resin from the layup has worked into the paint layer making it impervious to the citrastrip.. This is just a guess of course.. Looks like I'll be wet sanding for a while..

Has anyone had luck stripping paint on a Byron kit. I purchased the plane used and don't know what it was painted with.

My Arrow was painted after wards so i am sure it will come off as long as Citristrip dose not attack poly resin. Original builder said it was lightly painted as this model was meant to be prototype only....

Dang Lee, that is no good. Both planes of mine were painted out of the mold, so that sounds like it may be your problem.

Citristrip works fine on polyester resin made parts.

Davin,

Will the Citristrip remove paint from balsa with out damaging the balsa? I have a giant scale Lear Jet that the previous owner painted & he painted directly over the unglassed balsa surfaces.

Finished painting my plane (that I stripped above). Turned out pretty good, neat product, started stripping another plane also.
Daven,

Please tell me the steps & materials you used to repaint your first racer. If you used a spray gun please tell me exactly which one you used. The repainted racer looks INCREDIBLE!!!!

I tried using same stuff to strip the paint off from my Arrow that i used to use on my plastic models whenever i wanted to change the whole livery of the model. I used Oven cleaner spray "Easy Off" the blue can, it worked like a charm. At some areas where paint was tough i had to spray it twice and wait bit longer to bubble the paint before i scrapped it off with old credit card and kitchen dish cleaning sponges.

If balsa was painted directly without a layer of fiberglass, I would be hesitant to try the product. At least give it a try on a test piece before committing the plane. I am not sure how it would hold up.

I used a $25 spray gun from Menards. It is a 4 oz gravity fed HVLP automotive detail gun. These work very well, this is my 2nd one. The primer on that one was just cheap rattle can primer from Ace Hardware. The base coat of White was KlassKote epoxy coating, than the green which was PPG Concept autopaint, and then finished off with Black trim and Klasskote Clear.

Hi slevin1,

I would avoid using any chemicals on a wood surface. The wood will soak up some of the chemical with the net result the new coat of paint will be attacked.

Regards. Karl.

In stripping paint off balsa, you can use acetone or MEK and a lot of rags. These chemicals are standard paint solvents and completely evaporate and will not contaminate the wood. But wear gloves and do it outside.

On plain wood I would just sand most of the paint off and then glass over that. At least you know the surface is hard enough to handle the cloth.

Finally finished this project. Stripped down the beat up, old racer, and gave it a new paint job.

Be carefull leaving the citri strip on too long, as it will try to get under fiberglass. This wing / tail had some rohacell as the sandwhich material and it did get to it, which caused me a little extra work fixing.

Not a bad before and after in my opinion.

I tried the spray version of the citristrip stuff, it is really easy to apply and works great also

Excellent! Been hand sanding a KMP A500 off and on for almost a year and still only 1/2 done. This should speed things up considerably!

Just be carefull not to leave it on too long and take your time. It works, but is messy, don't try to do this on the kitchen table

Good luck.

Thanks Dave, got a jug of it while at lunch. Figure I'll start with 1/4 sections at a time to see how it works and things progress. Will let you know how it turns out..

sounds good, clean as you go or you will have a mess, small areas at a time are a good thing.
