Custom Paint Job on Regenerating Free Model Not Staying?

So I have a free model airplane that uses a regenerating script with a button. I wanted to do custom paint jobs for the fact of it will be a aerial warfare game. Problem is, when i was in Studio, I did the paint job, went into testing mode, and pressed the regen button to see if it would save the changes or not, it reverted back to original color. Is there a way to change the script to make it to where it regenerates with my custom paint job?

Regen Script-

local PlaneClone = script.Parent.Plane:Clone()
local Planekit = script.Parent
PlaneClone.Origin.Value = Planekit
script.Parent.Plane.Origin.Value = Planekit
local EnterOnSpawn = Planekit.EnterOnSpawn
local Button = Planekit.Button
local Main = Button.Main
local RegenGui = script.RegenGui
local PlaneClone2 = nil
local Active = true
--------------------------------------------------------
local RegenTime = 1 --Change this to how long it takes the plane to regen
local WaitTime = 5 --Change this to how much time you have to wait before you can regen another plane
--------------------------------------------------------
function DeleteIdlePlane() --This deletes any planes that aren't currently being used
	for _,v in pairs(Planekit:GetChildren()) do
		if v.Name == "Plane" then
			v:Destroy()
		end
	end
end

function RegenMain() --This function regens the plane
	local PlaneClone2 = PlaneClone:clone()
	PlaneClone2.Parent = Planekit
	PlaneClone2.Origin.Value = Planekit
	PlaneClone2:MakeJoints()
	return PlaneClone2
end

function RegeneratePlane(Part) --This is the main regenerating function
	local Player = game.Players:GetPlayerFromCharacter(Part.Parent) --This gets the player that touched it
	if Player then
		local Humanoid = Player.Character:FindFirstChild("Humanoid")
		if Humanoid.Health ~= 0 then
			if Active then
				Active = false
				DeleteIdlePlane() --This activates the "DeleteIdlePlane" function
				for i = 0,1,0.2 do --This makes the button transparent
					Main.Transparency = i
					wait()
				end
				if RegenTime >= 1 then
					RegenGui.Parent = Player.PlayerGui --The regengui will be put into the player if the regentime is more than 1
				end
				wait(RegenTime)
				RegenGui.Parent = script --This puts the gui back in the script
				local PlaneClone2 = RegenMain()
				if EnterOnSpawn.Value then --If the EnterOnSpawn value is true...
					coroutine.resume(coroutine.create(function()
						repeat wait() until PlaneClone2.Welded.Value
						while true do
							if PlaneClone2.Welded.Value
							or Humanoid.Health == 0 then
								break
							end
							wait()
						end
						onPlaneWelded(Player,PlaneClone2) --This activates the "onPlaneWelded" function whenever the welded value changes
					end))
				end
				wait(WaitTime)
				for i = 1,0,-0.2 do --This makes the button visible
					Main.Transparency = i
					wait()
				end
				Active = true
			end
		end
	end
end

function onPlaneWelded(Player,Plane) --This function put you into the plane seat the moment the plane is welded
	if Plane and Player then --This checks to make sure there is a plane and a player
		if Player.Character:FindFirstChild("Torso") then
			if Player.Character.Humanoid.Health ~= 0 then
				Player.Character.Torso.CFrame = Plane.MainParts.Seat.CFrame
			end
		end
	end
end

Main.Touched:connect(RegeneratePlane) --This activates the "RegeneratePlane" function when the Main brick is touched
